See this is what happens in the evolution of a player.
First, player joins the horde to gain knowledge, and protection.
Hordes take bases. Player learns limited strategies, how to attack certain bases due to spawns or terrain.
After awhile the player learns all the maps weaknesses and the best missions for which base captures. The game becomes routine.
Player expands, learns to fight and finds that air combat can never be completely learned or mastered in the MA due to all of the changing numbers angles people attack from.
Basically having a "map change" set-up isn't going to help because you know the next map as well as the one your "stuck" on. It too will have those same old hot spots, or bad spots depending on how you look at them.
