I main a warlock, but the supportive capabilities of the warlock are limited compared to shadowshot and force barrier. I play all 3 to be fair. The self rez is handy, but this raid isn't like the last 3 where you can get easily run over by mobs if your a man or 2 down. There are almost 0 situations where you can't wait for the 30 second timer to be up and go grab your teammates. I love my warlock to death, but he isn't the greatest for the raid
