maps are too small i fear

Nahhh... That's too much and maps are too small. It's about ground battle and infantry. Choppers are enough. If you wanna fly jets go play DCS or war thunder

Why not? A true Battlefield Experience. Not on evey map, but two jets, one per team, would be cool. So you will acquire new players that likes flying planes and give to them a total war experience with dogfights and bombing infantry or tanks. The size of the maps don't have to change, just increase the terrain and enable only to them more space where fly, like battlefield does.
