I am trying to get 10 BG wins for the nice challenge skin recolor, but it seems it's impossible to do anything as a destro lock in RBGs. I feel really bad for groups that think I am playing affli just to find out I am destro once I get inside of BG. I really feel I am the factor that brings down the whole group. I can't cast anything because I get interrupt 80% of the time. When I manage to get a cast of Chaos Bolt, if I am not specced in 75% more CB damage, I hit like a wet noodle. I am immobile, easily interruptible, my CC is useless and every DPS class shreds me to pieces.
I used to play destro in Wrath, while it was a monster DPS specc. Now even healers are better in DPS... How can I be useful as desto in RBGs? I can't even find a proper guide :/
