I would hope that Leaderboards and stats get separated out by game type. I would like to focus on 2 or 3 game types and be able to track my progress in each one rather than lump everything together. In C2 my win/loss ratio is horrible because of playing IA. My KDR is horrible because I play the objective in Crash Site and not team death match around the objective. Whenever I play TIA I always average around 2.25 KDR. So the generalized leaderboards don't often reflect reality at all.
