You use Second Chance so it's obv. karma.I've been killed by the RC-XD more times than all other killstreaks combined.
I hate the thing.
People who use it all the time are obviously terrible *******s.
I also found an amazing tactic for Wager matches. My friend and I hopped into a Gun Game and knifed only, we timed the game out and nobody got to 20. It was incredible!
