I prefer not to handle a space craft like a fixed winged aircraft. The issue with assigning roll to the keyboard is you only have 100 percent yaw only, which is really bad for tracking targets that can move freely in 3d space. and since lateral/vertical RCS and main/retro boosters could be used with the flight comp off, this is something my friends and I use extensively to avoid bullets.
as for the auto roll, will it still apply with a flight yoke or gamepad? and I have no clue how to mod it out and even if I did what problems that would create with multiplayer.
