Not in Trials, but yesterday in salvage I was always running into yellow bars. I mean constant. I was the only green bar. As my Hunter I was shooting this guy and doing miminal damage so tossed my knife at his melon. Straight between the eyes and still alive. He put a few shots in me and killed me dead. He then ran out the door and died. Stick around popped up on my screen. This had to be about 5 seconds after I got him with the knife. He managed to kill me, reload and run to the door before it registered. I'm thinking 3v3 may be buggered.
