Then what you have not experienced yet is when 1-2 fully maxed 20 HP stealth scoundrels have signaled you out as the person they will repeatedly kick in the back for 70% of your health per attack. You never get to fire off any of your good shots.
Ran into a couple trying to do this the other day. just told my team that if they see operatives on someone, use their pushes to get them off. Amazing how well that works. Especially if everyone doesn't do it at the same time and strings it together sequentially. You take the operative out of position to kill quickly and you have a dead operative.
