Actually, I would rather have a realistic sun.
Might scare off some of the lamers. It will make altitude useful, as it is IRL.
In game, at what altitude are most dogfights done? between 0 and 2000. IRL, dogfights took place at high altitude and fighters were designed to go higher. the ME-109 has a higher ceiling than the Spit, but that makes no differance in the game, ATM.
