OK so how many destruction locks have you seen raiding that use fire? Umm none

The part where destruction locks are over powered and yes i am a lock and yes i still say this, is the demonic sacrifice/shadow and flame build. All that lock has to do is spam shadowbolts. No dots no nothing. CoS if no other lock in raid casting it. and then spam shadowbolts. In a lot of high end game raids your locks are going to be at the top of damage meters jsut from this. shadowbolt shadowbolt shadowbolt shadowbolt. Be smart with your life taps and you will not run out of mana.

In response to skyzzor-

Exactly right, im sustaining 1600 DPS with just a curse up and then shadowbolts only in 25 man raids. DoTs = reduced DPS until you get the 2 piece T5 bonus, even then they're questionable.

I'm doing this using the Frozen shadowweave set + spellstrike with some kara gear + gruul sword, the rest is heroic drops or badge turn ins.
