Things that need fixed in the patch:
People using a keyboard to do some obnoxious looking clan tags/usernames on the PS3 version.
Glitching on levels, getting behind walls you shouldn't be able to and becoming invisible, etc. There are a few.
Team balancing. I've seen teams with seven players quite a bit. This can be the winning factor on game types that don't have respawns.
When a player willingly leaves a game and take the LOSS it gives you for doing so, don't put the player right back on the same server when they search for a new game!
Dedicated servers on the PS3 version, please.
Gimp the grenade launcher. Yesterday I was on a team where a guy with a grenade launcher took out the ENTIRE enemy team within three seconds of the match starting.
And as for maps, I'd like LARGER maps that aren't so predictable and not something where half of the people die within the first ten seconds of the game by blind grenades and grenade launchers.
