Hi dar,
I have no idea what is the best at this moment for pvping. All specs have a down side and a upside.
Aff:
Upside: Lots of dots, do damage when your stunned and awesome self healing the only spec that has a constant slowing effect
Downside: no burst damage so it take alot of time to kill someone and you screwed if you have 2 or more target on you.
Demo:
Upside: Lots of burst and dots combined, Alot of pvp talents and a pet with some strong spells
Downside: So slowing effects unless you glyth for it, Very dependant from 1 cooldown. No healing just healthstone and felarmor
Destro:
Upside: Some self healing, Lots of burst damage, Some CC, Can slow alittle, strong against casters
Downside: allmost no instant casts, weak against melee, quite dependant on immolate.
Personally i think Demo and Aff is the best but Demo might slightly better, i just hate it that demo allmost cant slow and has no self healing.
So my qeastion is what do you think is actually the best for warlock pvp atm?
