I hate to say this but, IMO, Lockdown needs some kind of Matchmaking system. I'm relatively new to this game (took a 1.5 year break on tom Clancy games for Halo/halo2) I keep ending up going up against level 40+ people that kill me in one burst(Higher upgraded weapons), where as it takes me 3-5 bursts. Its not fair that the "lesser" levels have to go up against that. Most of the people I've played who are 40+ are complete noobs but only beat me because of this unfair advantage.
Oh yeah and those claymores are F'ing annoying,bad kids spamming them all over the map and the gloating about getting kills really pisses me off.
Really my whole point to this thread is, LOSING TO NOOBS BECAUSE OF AN UNFAIR ADVANTAGE SUCKS.
