Readiness has been replaced by Blink Strike on the beta, which is very undertuned at the moment. It is on the GCD so if you consider it as effectively two "extra" pet attacks. In the span of a 3 minute window you would have 6 Blink Strikes for 12 extra pet attacks at the cost of 6 GCDs. By comparison, Lynx Rush would be 18 extra pet attacks at the cost of 2 GCDs.

With Lynx Rush already already known to be weak, Murder of Crows would have been by far the most damage for that tree, but it has been nerfed. I'm not sure what the armor formulas are now but I got some numbers on a level 85 target as a level 90. With 26405 AP each crow hit in the range 2685-2686. Number of attacks varied somewhat between 54 and 57. With 15619 AP each crow hit for 1691-1692; difference of 994 damage and 10786 RAP. 10786*(RAP coefficient)*(damage reduction from armor), (RAP coefficient) = 9.21%/(damage reduction from armor). Depending on how armor works now the RAP coefficient might not have changed since Rivkah's post but the base damage is obviously much lower. Does anyone know the boss armor and armor mitigation formulas at 90? I vaguely recall a blue post about it but could not find it.

Level 60 talent tree has two changes: Dire Beast has been moved here and Thrill of the Hunt has been nerfed significantly. I'm not sure if Dire Beast's damage was changed (level 85 target, 26405RAP = 13175 dmg hit, 15619RAP = 8205 dmg hit) but I was consistently getting 8 hits. Thrill of the Hunt now only works on Arcane Shot and Multi Shot instead of high focus abilities.

I'm not sure if this was viable in the first place, but it means you can't use a spec with TotH and Power Shot and then only use Power Shots when TotH was procced anymore. If you don't need the utility, Glaive Toss is the only ability that seems to be worthwhile for single target DPS, mainly because it is off the GCD. Target armor, Survival mastery, and weapon will all matter but it looks like the damage between Glaive Toss and Arcane Shot is at least comparable, with Glaive Toss costing 2 focus less and being off the GCD. If it's not worth using on CD it may be worth using in place of Arcane Shot as a focus dump at times.

On armor and armor values;
Armor for a lvl 93 target is 24,835 (Curtesy of Zeherah, confirmed by GC here.

If its more the math behind the reduction (as opposed to the specific value) I'm sure either Zeherah can jump in and provide it, or it can be found in this thread over on maintankadin (if you can read and understand "Theck'ish")

Frostheim was the one who gave me the armor number btw- not sure if he got it from testing or GC. He also gave me this as the armor reduction formula for level 90 players: Target Armor / (Target Armor + 46257.5). I'm not sure if it's exactly correct but it seems in the right ballpark.

When I'm testing on dummies I usually just work off of the damage reduction percentages and not the armor numbers. Usually it's not too hard to figure those out on a specific level dummy since you can just work off your expected white attack damage in the character screen to give yourself a good idea (I usually like to use a white weapon with a very small damage range). I've been doing most of my testing on the level 80 dummy, which seems to be about 82.78% damage reduction. I also have a number of 97.6% damage reduction on the level 60 dummy, but that one might potentially be more off as I did that testing awhile ago and haven't been using that dummy much lately.

Thanks. Theck gave me a slightly different value for "K" on twitter: 460203.33. Small enough not to matter much for our purposes (difference is about 0.03% mitigation). That would mean a mitigated hit would do 65.04% that of a non-mitigated it. I did the numbers again against the level 93 target dummy and got a simple two-variable problem:
26405*x+y = 2166/.6504
13121*x+y = 1179/.6504
RAP = 11.42%
Base = 313.8

I did the same for Dire Beast and its formula is unchanged (which seems to make it significantly better than the alternatives, suggesting that tier is due for review).

edit: Also it's worth noting that both the beast's and crows' attacks count as white attacks and can be glancing blows.

I thought it might be useful to compile a list of the level 90 formulas we know currently, so I put together what I have so far. I've verified most of these formulas semi-recently, but they do tend to change sometimes without notice, so take them with a grain of salt. Note that for multi-target abilities I have only listed the primary target effect.

One thing to note, I noticed is that all the weapon damage based shots I tested seem to use the aimed shot style of weapon damage modifier now, where it actually applies the multiplier to the entire shot instead of the weapon damage portion. I'm not sure if Blizzard intends to keep them this way.

This is incredibly useful. Thanks! I've copied your list below where I will annotate comments based on the simc implementation. I'll edit the post as implementation or status changes. I use "MATCH" to mean not only that simc agrees, but also that all the data was extracted from the client meta-data rather than from data gathering in game. While there could be a meta-data errors (e.g. tooltip issues), if the tooltip and in-game behavior match, that's pretty high assurance.

Hunter:

• Aimed Shot: (avg weapon dmg + RAP * .2 + RAP * .724 + 9970.4) * 1.6 - MATCH
• Arcane Shot: (avg weapon dmg + RAP * .2 + RAP * .0483 + 4611.3) * .65 - MATCH
• Barrage: (avg weapon dmg + RAP * .2) * 3.2 (total damage to the primary target over 16 ticks)
• Black Arrow: RAP + 4661.16 (total damage, split over 10 ticks) - MATCH
• Chimera Shot: (avg weapon dmg + RAP * .2 + RAP * .732 + 1794.67) * 1.15 - MATCH*
• Cobra Shot: (avg weapon dmg + RAP * .2 + RAP * .017 + 306.559) * 1.15 - MATCH*
• Explosive Shot: RAP * .311 + 517.21 (per tick, there are 3 ticks) - simc bug now fixed
• Explosive Trap: not yet tested
• Glaive Toss: (RAP * .05 + 218.102) * 8 (to the primary target, 2 will hit) - MATCH
• Kill Shot: (avg weapon dmg + RAP * .2) * 3 - MATCH

Pet:

• Bite/Claw/Smack: RAP * .36 + 329 - different
• Blink Strike: pet melee dmg * 2 - MATCH
• Kill Command: 1.8 * (.516 * RAP + 1021.96) - MATCH*
• Melee: RAP * .2572 + 560

Summoned Pets:

• Dire Beast: RAP * .5715 + 1246.5 per hit (may have changed since last test, does about 8 attacks)- I took these numbers from you.
• A Murder of Crows: RAP * .1142 + 313.8 per hit (based on Esoth's tests, 54-57 attacks)- I took the parameters from Esoth. simc models 8 summons attacking every 2 seconds for 16 seconds. That results in 7-9 hits per crow (though 9 is rare).

*For some matches, the RAP coefficient is buried in the tooltip only rather than an explicit typed meta-data field. Those are both more likely to be out of date and require manual propagation to simc code if the meta-data changes.

Explosive Shot
Simc is still using the Cata formula. In theory, it's also changed to ignite mechanics. Have you noticed that in game? That will be next on the MoP simc hit parade.

Claw
This looks very different. From the meta-data:
$M1 = School Damage: physical (2) Base Value: 146.004 - 207.945 (1) - average 176.9745
Description : Claw the enemy, causing ${$M1+(($RAP*0.40)*0.20)} damage.

This corresponds to: 176.9745 + 0.08*RAP. I'm pretty sure simc doesn't actually do that either, however, so I'll need to do more investigation.

I didn't test the changed mechanics in detail (just verified the formula was matching up relatively closely to my results), but I did verify that applying explosive shots before the previous ticks had expired would increase the tick damage on subsequent ticks. I didn't verify if the math on it was working accurately.

I don't recall the formula ever perfectly matching what was described in the tooltip on live either, although it's been awhile since I looked at it. I always wondered if I misinterpreted the way that formula was meant to work. The numbers I have are based on dummy tests so I can't say if the exact multipliers and +dmg are accurate, I can just say they're in the right ballpark and that testing at various RAP levels I was getting results which fit the formula. If I recall I think when you look at the ability tooltip the numbers it gives don't match what you get attacking the target, so it's possible the meta-data was just never updated.

The last shot has 4 ticks of 5433.5, the first of which happened to crit (hence 10,866). Thus, the data you posted matches ignite for shots of 4106, 4060, and 4530. The "Total" column is Damage * Ticks; that should be how much damage is remaining to be done. "After Tick" is simply the total after taking the tick represented by the line (i.e., Total - Damage). "New shot" is The Total from which the current tick will be computed (on the current line) minus the the previous "After Tick", all divided by 3. Thus, it assumes that the new Total is "New Shot"*3 + previous "After Tick".

Damage	Crit	Ticks	Total	After Tick	New Shot
4106		3	12318	8212	4106
4106		2	8212	4106
4072		4	16288	12216	4061
4071		3	12213	8142
5433	Y	4	21732	16299	4530
5433		3	16299	10866
5433		2	10866	5433
5433		1	5433	0

This doesn't mean that the mechanics are ignite mechanics, but it does work for this case, and regular dot mechanics does not work for some of the other cases (e.g., where tick damage it outside the possible damage for that weapon/PA combo.

Edit: StarFox pointed out that the 4530 above it too high for the variance allowed by ES. So the model is still up in the air.

As we talked in irc, ES is a clusterfuck at the moment, it seems random when ignite behaviour triggers. I worked out my screenshot.
My hunters ES tick range is 4050 - 4144 (should be 98 point range, so there is still 4 points of leeway up and down).
We start with a pool of 0 of course, ES hit is the process of adding to the ignite pool (base tickdmg * 3), a tick is when the pool ticks down. The damage when ES lands is HIT (+pool) followed by a recalculation of the tick dmg and a TICK (-pool)
Crit tricks only deal more dmg, the don't add or substract more from the pool than normal ticks.

hit	tick	change	Pool	next tick
0	0	0	0	0
4107	0	+4107*3	12321	4107
0	4107	-4107	8214	4107
0	4107	-4107	4107	4107
4072	0	+4072*3	16323	5411
0	4072	-4072	12251	?????

It seems like the 2nd ES did not even trigger ignite behaviour, there should be still damage left in the pool, so the tick should be way higher than 4k. So if we discard the 1st ES dmg we get

hit	tick	change	Pool	next tick
0	0	0	0	0
4072	0	+4072*3	12216	4072
0	4072	-4072	8144	4072
0	4107	-4072	4072	4072 (would be)
4076	0	+4076*3	16300	5433 (recalculated: pool/3)
0	5433	-5433	10867	5433
0	5433	-5433	5433	5433
0	5433	-5433	0	5433
0	5433	-5433	-5433	0 (faded)

This works out like a charm, the first ES hits for 4072, building the pool up to 12216. Then we have 2 ticks, which drain the pool down to 4072. After that the second ES hits for 4076, adding 12228x3 = 16300 and the tickdamage recalculated to 5433. At the end we have _4_ tick events, this seems to be a problem with refreshing so it adds a tick, but the damage als already calculated with pool/3, that's 5433 free damage that came out of nowhere.

In case Lokrick didn't notice yet, his question in the beta class balance thread on this topic recieved an answer

A few additional tidbits: Mechanically, ES does SPELL_DAMAGE on impact, and has two DoT ticks. Those go into the rolling "ignite-style" dot. It appears to reroll the damage that it injects into the rolling ignite, so the dot damage is never the same as the impact damage. I have an example in which the initial impact crits, but have not yet seen crits for either individual dot ticks or the injection into the rolling dot. I think this will only matter for FD if indeed there's no crit damage in the last two ticks of ES.



Edit: I got a sequence with a tick that crits (along with an identical one that didn't). Additionally, the initial tick damage is higher than the initial impact damage, thus reinforcing that the dot is a different damage roll rather than some function of the impact damage.
