Epic Falc Fail

So heres some background info. I was hanging with a few of my friends playing some invasion in matchmaking, i stole the enemy sniper and was using the plasma launcher. They just about capped the core but the falcon pilot decided otherwise. I shot 3 bolts at the Falcon and ended up just damaging it so i shot 2 more at it, which ran me out of ammo for both guns. We think the Falcon pilot was trying to protect his teammates but ended up blowing up the guy with the core and his bodyguard giving me a triple kill, killing frenzy, and prevented them from capping it....well until 2 more guys came up and finished caping it.
