I'm an IL-2 guy, a fanatic actually. I have some self imposed rules. First off I dont usually upp them at TT unless an airbase needs defending. Fights between GV bases I leave for GV'ers to have fun with. The same goes for fights between GV bases elsewhere on the map. Frankly TT would be better if there weren't any air strips at all, or something like it.
I try to extend courtesy even further. If a fellow Rook is strafing a Tank I either leave it for him or ask first if he minds if I attack it. I like to leave targets for the tankers too and not hog everything.
I dont even go to TT frankly. To much dweebery. At most I'll upp a fighter and leave the GV battles to the GV'ers.
But it would be better if there simply weren't any airbases on the Island. We should leave TT to the GVs. I agree.
