nothing can be done about it, as long as they are not openly cheating.
they are paying to play.
you can't tell a player how to play his/her game. that would be wrong.
It can be fixed...
It's called attrition warfare. Give each base, based on its size a set number of aircraft/vehicle points, All planes/tanks will have a cost to operate, late warplanes are more expensive... early warplanes are cheap. If you make it back to a base, the points for the plane go back into the force pool for the base you land at. You don't make it home the points are lost and have to be resupplied. We could take it one more step by replacing the current ENY. Instead of denying use to a plane based on your sides current population ( your team outnumbers every one)The game just makes them cost more to use, If you are on the side that is outnumbered your planes are gonna be dirt cheap.
So...
If you're on the side of the most players and want to fly at the P-51 you still can, it is just going to your cost base your more.
Want to bomb and bail you still can, but your side will have less planes to play with.
You want to furball? You still can but, eventually one side or the other is going to run out of planes and your base will fall.
