any class can pin down boss in cloud  by circling around him.concussion doesnt help that much as after 1.7sec boss have cooldown of several seconds when you cant concuss him.This coming from 25 concussion heavy who always tries to  circle around bossto keep him in cloud  when friendly medic throws antidote.
