IMO I think it would be cool if they added more perks and maybe gave you more weapons for going into prestige mode. Take out the Jaggernaut perk(Which wont happen) and maybe replace it with something else like armor you can equip. Kind of like RB6 Vegas. Have the customize character thing for Multiplayer like in RB6 Vegas, for example: Use the camera to put you face on the character, get to customize you clothing, guns, etc. If you get rid of the Jagernaut perk, the armor could replace that. That would make Multiplayer greater IMO. ALso if they have Vehicles in their game, have game types that dont allow vehicles so the people who dont like them dont have to worry about them. For example: Team Death Match w/ Vehicles and Team Death Match w/o Vehicles. Also would love some kind of weather effects.
All I know is my Shooters will be complete with Arma 2 and Operation Flashpoint 2 coming out. If I get this game, it will be to get online and not have to worry about strategy. Just pretty much a Run and Gun type deal.
