I understand your frustration with the team mis-matches, but that was always going to be an issue coming into the game nearly 2 years from release. As for what you're saying about weapons, I actually think you're wrong when it comes to Support and Assault classes, although faction specific for you at the moment. The M16 is possibly one of the best AR's in the game and the M27 is by far and away the best LMG imo.
