I have yet to have a FD work on Razorscale. Doesn't matter what phase I FD on, It will clear agro on the adds, never on Razorscale. Either she is immune or its a bug.

I have actually spent some time testing the ES + MD and found that the threat generated is more or less equivalent to the double of initial ES shot, and of course the consumption of the three charges.
Regarding the Aimed Shot i found no bug with MD in any of the fights and tests till now.

Concerning MD and the charges.. the mechanics are abit blunt to be honest.

For example you put MD on your MT and go for it..
*EXAMPLE 1* serpent sting, chimera shot + chimera serpent proc = 3 charges gone.
*EXAMPLE 2* explosive shot reaches the target, then the damage kicks in = 3 charges gone.

So.. just applying serpent sting to a target equals a charge as does applying explosive shot before it even deals any damage at all.

All in all, it seems much wiser to just go arcane, auto + aimed for a MD to assure you won't get some monster of a last tick explosive shot crit, 6k wild quiver proc or 7k chim serpent proc back in your face on a vital pull.

Just tested it myself to be sure and yes it's still bugged. 3rd tick of ES is after Misdirection fades.

Been a 'known issue' for 3 months without a fix:

World of Warcraft - English (NA) Forums -> [BUG] Misdirect-explosive shot

Explosive tick, autoshot, explosive tick, MD fades, final explosive tick.

Wouldn't that explain it?

It would but the thing is the none damage component of Explosive Shot triggers a MD charge which kinda sucks =) The actual application of Explosive Shot on a target.
It is pretty annoying on for example Yogg Phase 1 where you constantly MD big adds to the tank/s.

The application of ES consumes the 1st MD charge. The first and second tick of ES consume the 2nd and 3rd MD charges. The third ES tick does not apply to MD. This scenario assumes no other shots than ES.

The safest route is AS + Auto + AiS.

I've macro'd my pyro rockets to my aimed shot so I can get an instant 3 shot MD. Not as great for MDing on the fly during a fight since the rockets are likely on CD but it's great for pulls where I can hit one button, fire 3 shots and start running to my spot almost instantly.

Yeah, should've mentioned I tested this while running.

Will dot applications consume MD charges? In other words if I md->black arrow->serpent sting, have I just wasted 2 charges of MD and generated 0 threat? In OS (before 3.1) I used to MD->serpent sting and then kept running, and on omen the MT threat jumped up a few times before ticks started increasing my own threat.

I'm wondering if the hand mounted Pyro rockets are more dps than the flat 20 agi to gloves. Me being survival you get boosts to your agi so I'm not quite sure if the rockets would be straight up better than a regular +20 agi or not.

Anyone know?

Im no Mathswiz by far, but isn't it rather simple? The Hand Rocket has a CD of 45 secs. It deals 1440 to 1760 damage per use, 1600 on average. 1600/45=35,5 dps. The question is whether the Agility enchant provides more DPS for you. The Spreadsheet will answer that question. If it does trigger the GCD, the damage will not be worth it of course.

The rocket can also crit, don't forget and it seems to use the hunter's crit rate (this will need testing to be sure though).

I usually have around 50% raid buffed ranged crit but the rocket crits in the 20% range. I've been as low as 15% and as high as 30% on different raid nights when looking at all attempts.

Last night in our 10's run over 5 bosses I went 24 hits, 7 crits for 23% crit. I was probably around 45% ranged crit with the buffs I had.

Ignore the higher damage numbers on the second one, there are heart strikes in there from XT.

Overall the rockets typically account for about 1-1.5% of my DPS. Pretty good and I love watching the little rocket launch

I'm more inclined to believe it might use spell hit and crit. Last night over the course of a 3hour 25 man raid with 275 hit and Draenei presence I still had 1.2% missed and a 29% crit rate vs. my other shots which all ranged in the 52-62% crit range.

Pyro - 29%
Auto - 52 %
Steady - 60%
Explosive - 61%
Kill Shot - 62%

Talents modifiers (0/15/56) explain the higher crit rates of several of the specials but even compared to auto shot the rocket crit rate is significantly lower. I say spell hit and crit since none of our talents modify spell crit and my untalented crit rate based on gear alone is 29.29% (easily verified ATM via the bugged armory).

I don't believe it's spell hit. I have never seen a miss when checking recount or WWS. Is it possible that you hit something that was immune or something like that? I think hitting a banished target shows up as a miss.

Upon reflection the crit rate does seem a bit higher than what I initially posted. However the sample is still pretty small. Spell crit may be a possibility.

I remember reading this and being a little surprised they'd give us a point-blank shot. That it turned out like this on the other hand isn't a surprise at all. My guess is that even though they said they were "removing the minimum range", they only meant "removing the additional minimum range", so that it would be in line with our other shots.

Applying Serpent Sting to a target uses a MD charge before damage even ticks, so that would be a yes, sadly.

How do you get it so high?

Looking at my numbers (was doing both emalon and archavon tonight in 10 man), the pyro rocket went from 1515 to 2108 on regular hits and 2500 to about 2800 on crits.

Since it couldn't be the 7% extra bonus you get from Black Arrow/Noxious Stings (I got Focused Fire so it brings your bonus extra damage down 2%), I'm curious how you would get it that high.

I'm going to go out on a limb and say it's not possible unless you are hitting XT's heart or have a Rune Circle.

A few changes in 3.1.2:

Lock and Load - Changed to have a 2/4/6% chance when you deal periodic damage with your Immolation Trap or Black Arrow to cause your next 2 Arcane Shot or Explosive Shot spells to trigger no cooldown, cost no mana and consume no ammo. Down from 4/7/10%. (src: Wotlkwiki.info)

Go For The Throat: Explosive Shot critical strikes now trigger this talent.
Rabid: This Hunter pet talent no longer lists a percentage chance to be triggered, as that chance varies by the attack speed of the pet. (src: MMO-Champion)

Are they kidding with the LnL change? It hardly ever procs now and they're further nerfing it? At some point it won't even be worth taking.
