Armour lock to be changed, only 1 charge per life, and has to stay in it when deployed for the full duration.
Ranks to be put into the game, especialy for MLG. (Im getting sick of searching by myself, and getting put against a pro MLG team of 4)
If your searching by yourself, you get paired with people by themselfs or in two's.
Active camo not to have radar jammer. (Maybe make it so you can't camo snipe, very frustrating)
Have two 'Team Objective' playlists, one for flag and oddball, then another for all other objective gametypes, eg headhunter, stockpile, etc
More items in forge (people who say more money, they can't because then it will lag the map/game)
2 player theatre (4 is just stupid)
Friendly fire turned off in Infection.
If zombie quits in Infection, a Human shouldn't have to turn into a zombie.
Quit ban turned off. (1st, it doesn't work, people quit anyway, 2nd its stupid that your forced to stay in the game)
Some spawns changed. (Uncaged, you shouldn't be able to spawn behind someone)
More maps. (mostly map packs, we have too may forge maps and not enough real maps)
For the map packs that are out now, you must have them to play any matchmaking game. (8 and a half months after the first map pack came out, and we still don't have them in any playlist apart from 2 special ones)
Bloom is fixed or removed.
1 grenade should not kill you if your health is low.
Can't beatdown a sword lunge and survive.
