Lulz, that's not very nice. Also, he has more targets, it'd only take a couple lucky encounters for him to pass the opposing team.
Well, in a 3 vs 4 situation I'd back the 3. But an 8 vs 1 is pushing it. They would basically control every power weapon and could spawn kill the poor guy to smurf.
Lulz, if they're good maybe. But still, no one's perfect, it'd be easy for him to get kills if he's as good as I think you're saying he is.
