Well there are some possible solutions against strato buffs.
1) Even with norden, make all ground object dissapear when buff is above 23k. Its a ww2 norden sight, not the damn Hubble!
2) Allow players to purposely deploy SMOKE SCREENS. Get a tank and blow smoke all over the field (or introduce a smoke deploying halftrack or something)... say, green colored smoke
. That way nothing, not even vulchers would be able to see anything inside the smoke screen. Framerate? oh hell!
3) clouds? Add a cloud layer at 23k.
and lastly, make those buffs behave like buffs. Those things turn on a dime and are quite good at defending themselves against hordes of fighters. Lately ive seen buffs that spot incoming fighters from a good angle and they use their amazing rudder turns to have the tail gun face the fighter. Tactics? Yep, there goes the neighborhood.
PD: The B-26 is an awesome anti-buff interceptor. Get a gunner and start raking them other buffs from d1.2. Its like flying a heavy p-38!
