I have 206 Haste Rating, 5% haste from Enlightenment, my Resurrection cast time is 8.96 seconds.
With Borrowed Time buff (5/5) I have 7.17 seconds
With Power Infusion and Borrowed Time I have 5.97 seconds.

10 / (1 + 206 / 3279 + 0.05) = 8.986
10 / (1 + 206 / 3279 + 0.05 + 0.25 + 0.2) = 6.389

... Not entirely right, lets try the alternative

10 / ((1 + 206 / 3279) * (1 + 0.05)) = 8.96
10 / ((1 + 206 / 3279) * (1 + 0.05) * (1 + 0.25) * (1 + 0.2)) = 5.974

That seems better.

If that is the case, Enlightenment scales with gear, and provides 6% effective haste when you reach 20% without it.

i.e. (1 + 0.20)*1.05 = 1.26 vs (1 + 0.20 + 0.05 ) = 1.25.

That seems ... unintended.

I'm almost certain that is working as intended, unless I missed a blue post somewhere. I have not tested this lately, but historically haste effects were almost always multiplicative. The exception was anything which affected "crit rating", which worked additively. The way I remember is it that one haste effect is your crit rating, but your haste rating is but one of potentially many haste effects, all of which are applied multiplicative.

I just checked, and this is consistent with the desciption of haste on wowwiki.

After a forced respec to discipline for Sarth +3add, I wondered what good addons I could use to track disc-buffs/debuffs.

Would like all of it to show, either in grid or in any other way just wondering what others use.

Any input?

I use Grid, with custom Auras (Add Buff/Debuff). Remember that after Adding a Buff/Debuff, you must Choose where to display it.

Add Weakened Soul as a debuff, put it on Low Priority, make it display as Center Icon and Weakened Soul is fixed.

Then you can add Power Word: Shield as a Buff, Prayer of Mending and Divine Aegis, Make sure you set their priority in the order you wish them to be, and add them as "Lower Rigth Corner" buff. Putting different colors on the dots help too.

I already have that but I only have a timer for renew, can't get a timer to work for weakened soul and the other buffs cause theres no plugin for it.

On the topic, is there a mod I can that will give me select buff durations in a place I pick?

As an example, I'd like it to display Holy Conc., Surge of Light and any chance on cast trinket that procs without seeing the 500 other buffs I get throughout the fight. I generally try to stick to the default UI, but Blizzard's scrolling combat text gets spammed way too fast.

Check out Power Auras, it's pretty fantastic for things like this.

If you can spend the time to configure it, SpellReminder does this too, and is incredibly flexible and powerful. It can track cooldowns, hots, trinket effects, etc.

So would that mean a haste value of 2.22 in Rawr 2.1.3 would be 1.11 in Rawr 2.1.4?

I'm pretty sure it is.
I played a hunter for TBC, and it was clear that different haste effect are multiplicative.
The reverse part of it is obvious : 50% haste doesn't mean that you cast twice faster, but only 1.5 faster : haste just divide the casting time by (1 + %haste).

Another point of view is to remind that haste doesn't change the "size" of the heal (or damage) of the skill : therefore, the hps (or dps) is multiplied by (1 + %haste).
And haste always provide an exact in % increase to the maximum hps or dps.

The only case where it isn't the case is when you consider adding haste from the same effect (mainly from gear). Then the returm is not linear in a relative measure, but dicreasing (in the same way as for crit).

I didn't think it would be that easy. I'm finally running the peeps with kids naxx 10 next week, and I've been so focused on helping my main tank get gear that I didn't take time to wonder what was wrong with my gear list.

The Cooldown of COH has been confirmed and its duration will be 6 seconds
- source: MMO-Champion BlueTracker - CoH CD - What will it be and why?

The main reason offered behind not restricting it to a party based heal rather than a "smart" heal (my impression is that the majority of COH Priests were happy with the old, party-based restriction) is that their design goals is to reduce the need to set up specific groups and allow greater flexibility in healer UI buildings.

If this is the case, do you think they will/should remove the restriction of party-only heals for Holy Nova (and my preference) POH? I mean surely these go against the same design/UI goals.

Even for things like Shaman's Mana Tide, I see no reason why that has to be party based - it should always target the shaman and then give mana back to the 5 people in the raid with the lowest mana (like Replenishment).

Holy Nova and POH should be raid heals with the Priest always healed and at the centre of the area of healing.

Not entirely, but for me, it seems like Haste and Crit are worth about the same now.

I thought the problem wasn't so bad last time I checked, but after seeing some very werid numbers I decided it might be best to doublecheck. Sorry for not believing you first time.

Removing the party restriction for Prayer of Healing, imo, will just return us to brainless healing. I'd just sit in the middle somewhere and spam Prayer of Healing. It's far too powerful because of its large radius.

Holy Nova on the otherhand, I agree with the nerf to CoH, the party restriction should be lifted. Otherwise we'll just start spreading out priests and putting 1 priest per a party or something of the sort.

In terms of crit and haste, wouldn't crit be a bit more valuable now since it will still meaningfully affect CoH while haste won't have any direct consequence?

If this is tested to be the correct formula for haste buff stacking then I would like to assert that disc priests should begin devaluing haste after 290 haste. Using the multiplicative formula, solve for haste on instant/1.5s casts to reach gcd. Assumed haste buffs are 5/5 enlightenment (1.05), WoA (1.05) and 5/5 borrowed time (1.25):

In my current rotation the amount of instant/1.5s casts spells that I have the borrowed time buff up for is rough 1/3 of all my spell casts, accounting for about 1/4 of my total time spent casting. Stat weights should be adjusted accordingly.

Basically any priest will have 15-16% crit rate in raids even if they don't gear for it, and it should be enough to want to have IHC with a normal rate of tank heal assignments. Also with the cd on CoH I think there will be more spots where we want to throw Flash Heals, making IHC shine even more.

All in all, I don't really see any realistic situation where you would not want it as a deep holy priest even at minimal crit rates in a very near future.

0%. In other words, you always want to max out IHC if you're deep holy. Regardless of crit rating.

Quick UI question.

Is there a way to make Grid or some other addon show when someone is frost tombed in the KT fight? My group had our first attempts last night and would have downed him but for one bad frost tomb that wasn't caught fast enough.

/grid config
Status->Auras->Add new Debuff->Frost Blast
Frame->Center Icon->Check Debuff: Frost Blast

Any addon(s) that only tracks YOUR PoM?

I use Prayer of Mending Tracker (PoMTracker 2.5), its very clean.
