Only Corruption and CoA were changed (95% and 120%).

Also I'm pretty sure UA is now affected by spell damage, considering I got *hit* for 2805 for dispelling an unstable affliction last night, way more than could be explained by Shadow Mastery.

I will withhold my related comments on game balance for my personal diary.

So it seems that with 2.0.3 the following changes have happened:

First, the base AOE penalty is now 1/2 instead of 1/3.

Second, if an AOE spell lasts for 8 secs in some way, it gets multiplied by 0.83 in addition to the 1/2 AOE penalty. No idea why, but this fits consecration, rain of fire, flamestrike's DoT part and blizzard. This might just be a bug, or it might represent another way to calculate the coefficients for which a cleaner formulation isn't clear yet.

Third, some warlock spells and one mage spell have been messed with. The afflicted spells are corruption, curse of agony, soul fire, curse of doom and pyroblast.

(edit: more spells were messed up)

Things seem to be relatively clear, but I'd appreciate some help with a few spells. :) In the following I've noted the expected coefficient and derivation for easier testing. Most of these should be quite easy to verify. Thanks in advance.

Warlock:
Unstable affliction - 120% / ?? (18/15 - proc apparently scales, but dunno how)
Shadowfury - 19,3% (1.5/3.5 * 1/2 * 0.9)
Dark pact - 96% (custom)
Incinerate - 71,4% (2.5/3.5)
Seed of Corruption - 120% / 21,4% (18/15 - 1.5/3.5 * 1/2)
Pet scaling (apparently it's enough to look at the pet tab once to verify this ;))

Priest:
Power word: shield - 10% (custom)
Holy nova - 7,1% (1.5/3.5 * 1/3 * 0.5 - aoe, heal, both damage and healing)
Holy fire - 73,5% / 17,7% (402/547 * 3.5/3.5 - 145/547 * 10/15)
Prayer of healing - 28,6% (3/3.5 * 1/3 - aoe, heal)
Lightwell - 0%
Circle of healing - 14,3% (1.5/3.5 * 1/3 - aoe, heal)
Binding heal - 42,9% (1.5/3.5)
Prayer of mending - 14,3% (1.5/3.5 * 1/3 - "aoe", heal)
Shadowfiend - thoroughly unknown, probably 0%

Druid:
Tranquility - 22,2% (10/15 * 1/3 - aoe, heal)
Lifebloom - 46,7% / 42,9% (7/15 - 1.5/3.5)

Paladin:
Exorcism - 42,9% (1.5/3.5)
Holy wrath - 28,6% (2/3.5 * 1/2)

Shaman:
Flame shock - 21,4% / 17,1% (50% * 1.5/3.5 - 50% * 1.5/3.5 * 12/15)
Searing totem - 367% (55/15)
Fire nova totem - 21,4% (1.5/3.5 * 1/2 - aoe)
Magma totem - 66,7% (20/15 * 1/2 - aoe)
Healing stream totem - 133% (60/15 * 1/3 - aoe, heal)
Fire elemental totem - no idea
Earth elemental totem - unknown, if any
Water shield - unknown

(edit: searing totem, unstable affliction)

Tranquility is now 8 second duration, so it's now 17.77% (1/3 * 8/15)

Is this 1/3 multiplier new?

Is this correct? Is the [* 0.5] modifier new in 2.03? I haven't whipped out a calculator since 2.00, but I could have sworn that the modifier was 400% due to some of the regularly 10k dooms that I was getting on PW and the like, and the 29k dooms on Thaddius.

If the *0.5 modifier is there, does anyone know the reasoning for it? CoD doesn't heal, so it doesn't fall under the dmg/heal rules, and it can't be for PvP balance since CoDoom isn't castable on players.

Yes, curse of doom is now only 200%, instead of 400%. I don't have a good explanation for this, because it's not related to PVP in any way/shape/form, and that's where the rest of the nerfs came from.

It is now always better DPS to cast Curse of Agony in PVE than Curse of Doom. My CoD damage was previously around 5500 on normal mobs without any debuffs, now it's around 4400.

This is more than likely not true, but is it true that a shaman's Flametongue Weapon is affected by +spelldamage?

That might actually make it a bit more well-loved...

flametongue and frostbrand affected by +dmg since shaman patch review

So now that Amp Curse works on Curse of Doom, it might still have it's uses in PVE. With 607 shadow damage and SM, normal curse of doom's are still only hitting for a little over 4k, but Amp'ed they hit for 5500 or so, and with a ToEP for just over 6k.

Also, I'm not really sure how the dispell damage for UA is calculated in regards to +damage percentage. With +803 shadow damage (trinketed) and CoS, I had one crit for 4985. That's more than 127% damage being applied, which is what the DOT portion receives. I heard it might be related to CoS stacking twice, but I'm still getting numbers higher than they should be without CoS on the target. Really weird, but I'm not going to complain. Just wish more mobs dispelled themselves... ezmode grinding would be hot.

The damage coefficients was found out a while ago. I believe Flametongue gets 10% and Frostbrand gets 25%, but that is just a memory from when I used to play Shaman.

If you wanted to test it, use each enchant without +damage gear for about 1000 hits, then with +damage gear for about 1000 hits, and compare results. Or trust others did the work correctly ;).


On a different topic, which mobs try to dispell themselves (for sweet UA procs)?

I wanted to confirm about AoE scaling. Is it 1/2 or 1/3 of +damage? If it is 1/2 than some percentages on first post seem off.

Also can someone explain again the maths behind Pyroblast's +damage scaling?

It is 1/2. Looks like Jaete just hasn't updated some of the %, in particular, Cone of Cold, Blast Wave and Dragon's Breath should all be 19.3% (1.5/3.5*1/2*.9).

As for Pyroblast, it's easiest to consider the DD and DoT portions as two seperate spells.
The Pyroblast DD receives 115% of +dmg gear.
The Pyroblast DoT receives 20% (5% per tick, 4 ticks) of +dmg.

Updated with newest info, thanks everyone. Still looking for confirmation for all the stuff I asked about here.

Pyroblast used to make sense; it used to be 6/3.5 * 75% for the initial damage, and 12/15 * 25% for the DoT, where 75% and 25% are how the base damage is distributed. The initial damage coef was changed to 115% in a patch recently (warlock's soul fire coef was changed similarly), but the DoT part left as it was.
