I also think logistics should play a much bigger role. One idea for this is to allow the building of FOBs with a repair station as a deployable asset (plus all the other goodies for defending a key position). This way armor devisions can repair and rearm without returning all the way to main.
With greater asset diversity and a reliance on good logistics, there would be many different ways to gain an edge. You can focus on the air battle, solid logistics, or good ol' fashion proud armor. The team which balances these all the best wins the round.
