What do you all think they need to fix/add to GTA in a patch that would make you cry for how happy it would make you?
I think:
-Fix ranked party groups (Allow parties to use ranked co-op)
-Make actual restraints on small maps so people can't run out of the area and drive away
-Add more small maps (Central Park, a Parking Garage etc...)

Any other ideas?

Ranked party groups I'm definatley up for that one!

Also, the biggest issue for me would to change the way the Lobby works, you should have some kinda options so you can search for not just gametypes but certain options in the gametypes, if you know what I mean! I hate clicking on say Race for example, then all of a sudden the race starts as soon as I get into the lobby, I don't have a clue what I'm going to be driving or what track or what conditions etc

yeah, i know what you mean. also, I'm tired of searching for a race and it starts as soon as I join so I have the crapiest car or the host takes an eternity to start it.

Another feature: A main multiplayer lobby, I hate getting disconnected, then going back to singleplayer, then fumbling with my cell, then waiting again.

-Clan Support like Saint's Row's

If they don't add ranked party coop, how about an option to boot players from coop?

I vote for a much more user friendly lobby. I don't mind connecting through the cell phone, but make it so it doesn't take you back to single player.

Yeah they need to fix the disconnecting. I get disconnected so many times when I play. Thats why I stick to saints row.

...allow similar trueskill to play with eachother

all good ideas.
we need a patch like this soon.
