26 peeps, I waited until started mashing each other (used Invis on belt (engineer) and Noggenfogger to make myself smaller), they all start hammering on another, when I see two-three people together battling it out, I pick the highest health target and kill him/her. I repeat that until there were like 5 left. Then I popped my cooldowns and won it all.
So practically like a rogue, except I was visible. Grounding Totem works so good on those nasty grips from DK's.
