Yes its the bane of my existence in the crucible. always I'm out gunning someone and they can just press a panic button and stop me In my tracks. I've even shot a gg at a titan but he still survives and gets the fist of panic on me. It's mainly the people that see they have a super and use it on the first person they see. Fist should be saved for heavy ammo or control points that's where there most useful.
