Seriously Gay...

I concur....

I don't really care for playing ranked..... it's not a priority and plus I suck with everything but the shottie and the torque bow, so I'd never get them...

anyone who "seriously" has this is lame and needs to find a real hobby lol

I'd have this achievement a few times over if you could get it in player matches. There's absolutely no way I'm playing Ranked long enough to get 10,000 kills. It was bad enough playing till I got the sniping achievements. There's just way too many people that are either trash-talking asshats, quit when they start to lose, or worse, glitch out of the map every round to get a draw. It's just way too infuriating, and I'd end up breaking multiple objects if I tried to get this achievement.
