I love Ice Breaker for all situations. I do switch to a different sniper when element shields are involved, but otherwise I only use Ice Breaker. Ice Breaker is what I use all the time in crucible too. Some people call it camping, but it takes a lot to piss off a whole team to the point where they all need to attack you first before they can progress to the next objective in control. It's a good strategy if it lets my team take the other team's points without having to worry about the ones we own! Thoughts?
