Weapons of light and move away from bubble and one hit people with ice breaker. If you stand in a bubble you just sit in your bubble it's user error not the weak class. Some people get 5+ one hit ice breaker body shot kills from a single bubble. I got about 11 once back when the big maps were in the game. It's super useful on anomoly. Put bubble uutside hallway, get weapons of light, one hit people on b or the Enemy end of hallway.
