This is nothing like Brink. Multiplayer should be completely seperate from things like co-op. Otherwise people just use co-op to reach a high level but they can't put up a fight in multiplayer. Especially if they go into your stats. You get people boosting
their k/d all the time on co-op if that happened. Only reason it could be done with brink was because there was no k/d system and everything was just based on the points you get rather than the kills as well.
