This isn't an exploit, it's damn good teamwork. I mean it sucks if you're on the receiving end of it, but there's something to be said for a team that came to win and know exactly how to do it without server lag, glitches, or any of that nonsense. Personally If it were me, I'd stop feeding them kills and just stay clear of their hardened Titan made orb dropping doomsday bunker. Sure that match is gonna suck, you may end up having to wait until the timer is up or maybe the opposition will start to get antsy and move about. But it's a single match. When it's over you can just return to orbit, re enter, and hope you don't run into those cool cats again. Or maybe take notes on their strategy, build your own team, and dominate! The game is only as fun as you want it to be, just sit back and laugh at the bad matches, cheer for the good ones, and have a good time! Party on Garth!
