I taunted a voidwoken bug only for it to run past my incarnate and hit other people. It doesn't even work really. It seems to make them more likely to hit you, but whether they hit you or run away from you feels completely random to me. And then when you get taunted it makes me lol tbh. "doing totally random nonsense" is an accurate description of the taunt debuff, at least when it's on your party members anyway.
