My worst KQ was when in mara we got stuck with 6 clerics who all tanked instead of healing thinking that themore they fight the better the prize they get. so the tank got killed by marlone all 3 times and wasted his hearts. so WE ALL FAILED!
That reminds me of a time when I had to tank Mara and Marlone for both parts because the group I got in sucked big time. The Clerics weren't much help so I had to heal AND fight. I was even forced to lure once because all anyone did was stand around and bicker about who would lure. We won but i'll be damned if I ever do something like that again.
