@Keiea: First off, grow up, extreme expressions happens, it ain't making anyone a retard, and the fact that people like you eagerly flame others just makes this forum less appealing to other users. Shame, isn't it?
Second, learn to get facts before posting anything. Stop taking numbers straight out of the air. How can you ever claim that fire is 200 dps greater than shadow, that's just ridiculolus
and I expressed myself very simple, simply because I am _VERY_ convinced that shadow is so much better than fire. Why bother writing a long reply to the 876321234567'st thread going like "hi is fire better than shadow just wondering lol"? Google it, man, go ahead already! (no really, don't do it, I did it for you, so keep reading).
3: it's not "my" math, I didn't do it, but granted, I should've posted something to convince the guy asking, even though it's cba since you can EASILY dig it up on the web (as stated before). I'm not gonna post any weird, long math formulas, you can do that yourself if you are so convinced that Fire is better. a^2+b^2=c^2=shadow is betterLol!
Anyways, here goes:
(this is copypasted by the way, why re-invent the wheel)
a lot of people are claiming that Incinerate is better then Shadow Bolts for the warlocks dps, the problem is that if we switch to Incinerate we will gimp the rest of the raid. Shadow priests wont be getting ISB on the boss, which leads to them doing 20% less dps, giving their group 20% less mana etc.
Shadow Bolt is 2,5 sec cast specced, it gives 15% more spelldamage benefit compared to Incinerate, it adds Improved Shadow Bolt debuff that gives 20% Shadow Damage taken and lasts for 4 charges and isn't consumed by DoT's and channeled spells. (even though DoT's DO benefit from the ISB while it's up).
Incinerate is 2,25 sec cast specced, it got a 10% multiplier from talents and gains 5% more damage from Mages Scorch, it doesn't boost any other class but the warlocks, Immolate is required to be up to maximize the dps from it. The pro part with this is that it doesn't require a shard to Sac a Imp compared to a Succubus.
Ok, now i've stated what i think about our main dps abilities, lets go to CoD/CoA, If you're using CoD and ISB is up on the target when it proccs, it does 35% more damage as a shadow warlock compared to a fire one. (ISB+Sacced succu).
And when it comes to haste gear (which you gain from the new sunwell loot):
1% haste on Shadow Bolt reduces the cast time by 0.03 sec compared to Incinerate which is only 0.025. So lets say you got 10% later on in your final gear setup, your Shadow Bolt cast time would be 2.20 vs Incinerate thats 2.00 sec.
Edit: Im not counting BL because it simply increases the warlocks dps by 30% no mather what spell you cast.
So my conclusion: Shadow Bolt does 5% more damage then Incinerate + it gets 15% more spelldamage gained per bolt AND CoD does 35% more compared to fire specc, and what do you gain with fire specc? YES! 10% faster Incinerates with 10% more fire dmg to them.
