The lag and the kids who constantly rush B and give the other team kills. Last night on blind watch, I was stuck on the A side, I swapped over to my titans striker class and rushed around to the bottom of B stairs where the other team was all sitting, sniping. They were all scoped in, I super 4 of them, they stand there for about 5 seconds as I attempt to melee them, and then all of a sudden I drop dead. Those 4 were the only ones with full red bar. Didn't get any kills when I super'd them and of course when I came back my super was gone.
