Ah, you wish mature, fair minded debate? Im sorry, you have this forum confused with Yale or Harvard lol Hmmmmm. Well I dont have very many gripes, especially after seeing the proposed tweaks.
You know where "proposed tweaks" are located? Please link

LACK OF:
-of teamdeath match
-one shot kills
-one man wolfpack style multiplayer gameplay
-not being able to stroke my E-ego with 5 levels of prestige
-jumping and grenade spamming is no longer a valuable combat technique
-Adding an emphasis on moving AND shooting,
-teamwork
-being able to reflect myself in the game with character customization
-class based gameplay
-maps have a different feel (generally speaking) every time I play them.
-Not looking at "photo-realistic" graphics
-small gems of comedy ingame
-the PSN community.
-weapons have distinct feels to them
All these are my PROs.
My CONs are:
-No lobbies, matchmaking, or party system.
-texture pops
-more maps would be nicer, but it's not a deal breaker for me
-Having such a cool environment, but only knowing a tiny bit of information
