I know it sounds weird myself too... but I did see it happen .. 100% positive.

And I know it's a bit risky to say stuff like this, because I'd find it quite hard to believe too if someone else said it.. but I'm basically just asking if someone else has noticed something similar happening too with 2 haste rating buffs on himself.

Edit: Let me requote what I wanted to say before I get more "zomg nub u r retard it r not posble!" replies.

Has anyone else noticed some weird cooldown / gcd bugs with both heroism & quag's eye proccing at the same time?

I've had Quag's Eye proc during Heroism. I recieved "This spell is not ready" error message while spamming Arcane Blast.

Heroism reduces the global cooldown. I haven't checked to see if it reduces global cooldown on everything or just spells with casting time.

After talking with a Paladin, Scrolls of Binding Light did not reduce the global cooldown for him. I need to ask a friend with a MQG to see if that works or not, as I don't have one. Quag's Eye and the epic sword definently do not reduce global cooldown.

Heroism / Bloodlust absolutely reduce the GCD globally on spells. I refresh all of my DoT's faster in affliction spec, casting time or instant. It is quite noticeable.

This makes it more than just 30% DPS increase for me, since I reduce my dot refresh cycle by 30% which increases my shadowbolt time by some amount AND the shadow bolts come out 30% faster.

I've killed heroic quag a ton of times now, no drop for me. I'm saddened to hear that it doesn't affect the GCD like Heroism. It really should.

Wait a second here.

You are maintaining that Bloodlust is causing DoTs to tick faster as well? I see absolutely nothing that would make that seem plausible in the spell effect, even if it were perhaps a desired consequence. I don't know that you are wrong here but I'll need more than "It is quite noticeable" and by that I mean actual combatlogs if you can.

I just stepped through two stripped combatlog of my own and I see absolutely no evidence of bloodlust affecting other people's DoTs.

EDIT: To clarify, I looked at DoTs started prior to the bloodlust and DoTs applied while lusted and saw no notable difference from ones outside the bloodlust effect. I looked at SW:P, Immolate and Corruption because they were handy. I did not do a formal statistical workup but 30% is a non-trivial amount and would have shown on casual observation.

No, I think he's saying that he can put his DoTs up faster, since the GCD is reduced.

Ah, well that makes sense at least! Sorry for the confusion but I was reading that as you were refreshing your DoTs more often rather than the time spent actually refreshing them was less.

I guess "dot refresh cycle" can mean different things to different people =)

Odd question, but has anyone observed what happens with Improved Slam under Heroism/Bloodlust? The cast time on an Improved Slam is 0.5 seconds but it always limited by the GCD of 1.5 seconds. What would Heroism do to/for Improved Slam in this case?

If nobody knows I will try it for myself asap.

Heroism will reduce both the cast time on Slam and the GCD, so you still will get "not ready yet" errors if you attempt to chain-use it.

Quagmirran's Eye does not reduce global cooldown. If your lag and spellcast is greater than the global cooldown, you will percieve it still working at full effect. All the proc haste effects work the same way, afaik.

Heroism/Blood Lust does reduce global cooldown. I'm unsure if the old pre-TBC trinkets also reduce global cooldown, but I'm begining to think they don't. Unfortunately, I don't have a MQG to test with. It could be that the Scrolls of Blinding Light does not because it's limited to just healing spells.

DOT REFRESH. A.K.A. Global cooldown. The time it takes to refresh instants is # of dots * (global cooldown + X) Where X is lag/reaction time. It is quite noticeable that my cast time dots (immolate, unstable affliction) as well as the instants (CoA, Corruption, Siphon) all cast faster.

Cast faster does not equal tick faster.

That is what I am saying. Even with Heroism also applied, Scorch casts faster than the Global Cooldown.

Northerner's correct. TheOnly's DPS gain is:

DPS gained by having extra shadowbolts in cycle / Original DPS of cycle

So if TheOnly was pulling 700 DPS, and managed to sneak in 70 DPS sustained due to procs and faster DoT application resulting in more shadowbolts, he would have increased his DPS by 10% due to the proc. More likely, the gain is smaller (3-5%).

We've run some numbers in the similar spell haste thread in the Class Mechanics forum, and the proc is certainly a DPS increase, but somewhere in the range of 5-6% due to the proc, *if chaincasting fireballs*. I don't see how it would be any higher for a DoT warlock, much less 5x so.

edit: Haste (magical) and DPS is the link I referred to. Nothing superstar-ish in terms of theorycrunching, but the results are approximate.

No you're right and I was wrong about the > 30% boost. I did some calculations I was going to post here, but it got unwieldy and didn't. With a 5-dot spec (41+x/y/10+z warlock), heroism does not increase dot DPS at all. It increases the time for the filler spell by 14%, meaning that shadow bolt damage goes up by 48%.
Shadow bolt is about 40% to 50% of the dps in such a spec, and it would have to be 62% or so for it to balance out to a total of 30% damage boost.

Heroism ends up at about a 20% damage boost for affliction warlocks. For destro warlocks, it would be 27% or so (they get best dps while still using corruption and immolate, no matter what spec, and with or without heroism).

I did not model the increase in improved shadow bolt uptime. You could use the new warlock spreadsheet on these forums to do that though. It ends up being relatively insignificant in general though, unless curse of doom gets lucky.

Spell haste should still decrease the global cooldown by the same ratio as the haste, it only makes sense to turn up the speed on everything universally.
