warlock / improved soul leech and soul leech

[Dotndirty]

do these stack with other classes versions and do you think its worth having .
can some one please tell me where i can find a spell rotation that actually puts the dps out that doesnt get overrided by another class.(point meaning coe gets nurfed by boomkin, cusre of doom pretty much useless/ coa and corruption wast of gcd.) im destruction and i feel like tard on the dps meter at 13-15. which means im not doing something right. gear is part of issue i agree. gems maybe too . and how much benefit is spirit for locks ?

I'd recommend EJ for research. But, as I said in another thread, don't just listen to what everyone says...do your own math. The rotations are typically good to follow, but everything else still requires some of your own legwork.

Use this to check info and rotation:

Use this to check your gear and how it CAN improve: (again do your own math and testing)
