As for all specs in pvp, i think warlocks are nerfed. I am going to talk about destruction in this thread specifically, comments made may apply to other specs.
Melee vs My Pet: ret pallys and Deathknights 1 burst it for fun... i consistently witness it get murdered.
VS. Ret pally: My survivablity compared to BC is drastically lower, if the ret pally has gear, they can usually burst me while in 6 seconds (while stuned) however if i can get out of this stone alive, i can usually deathcoil fear my way to victory
VS. Rogue: Ok this is my biggist complaint, i have not yet killed a rogue 1v1.. the only time i have ever killed a rogue was when it wasn't attacking me. I
VS. DeathKnight: Probally the biggest complaint for arena, death grip into him and partner, end of story, if that does not happen than i think they are reasonably balanced vs casters EXCEPT the improved magic immune shield (unholy), Although it doesn't happen often, when it does it hurts
Suggestions: Some kind of defense for warlocks would erase all of mine and other warlocks complaints, demonic circle and fear dont help our Defense problem, we need something new. Also pets definitely need a health and armor bonus to stay alive.
ty for your time
