only bad warlock use sunsinger mate especially if your only using it for the revive. what i have realise is that the more you use sunsinger the more dependent you are on self res, so the more you allow your self to die, basically you know you can die so you play like shit. i do entire raids and void nightfalls with void walker and barely die, on these things you shouldn't be dieing anyway, if you do you don't deserve any of the rewads. don't use sunsinger for a week and it'll make you a better player.
