I have never seen a warlock use the skill where it buffs ur team mate bcuz it is so useless with its low rang and most of the time u can't tell if they r using the skill unless u check them or they tell u. And a titans defender shield just annoys me alot bcuz if they pop there shield right next to me when I'm behind cover and shooting a boss, I have to wait till the bubble is done to shoot at the boss bcuz I can't shoot through the bubble and if I walk out of it there is no cover and the boss can kill me.
