This is actually bothering me now after looking that up earlier. I wonder if I should start a different topic on it.
Every scrapper set that has a taunt aura has no damage aura. That can't be coincidence. The reason this bothers me is because scrappers already have the worst versions of damage auras out of all the melee classes. Tanks get 50% bigger AOEs, yes? Brute's damage auras get damage buffs via fury, yes? Well, scrappers cannot get their damage auras to crit. Someone correct me if any of this is wrong.
