Modern warfare is an amazing game that has been crippled by the implementation of dedicated servers which don't allow players to rank up. Ranking up a character is the biggest part of the game but the only way to do this is to endure the slow matchmaking and laggy games in the present peer to peer system. Many other games, (including Black Ops) offer this type of feature so there can't be a technical barrier to implementing it. Allowing dedicated servers to increase player rank will extend the life of this game and greatly improve sales of DLC. Please Infinity Ward & Activision, make this small change so that MW3 becomes the game it should be - we will all be better off...
