Yes- agree about the friendly collisions on the ground. That's the way FA was - Collisions were only active once wheels were off the ground. If we can't do the same here, then it would be chaos on the ground due to the spawn as shifty mentions.
But if we can enable it once wheels up, that would be the way to go. Then if Crazy cuts in front of CAP when he's on a con's six, CAP can just run his prop right up Crazy's...well...you get the idea! LOL
A plus is that it really cuts down on ganging - once folks get used to it then they are more likely to save their alt and cover you like they are supposed to instead of cutting in and risk a collision.
As far as killshooter goes, FA had it enabled for years, and folks were always complaining. With Killshooter on, some chump can cut in front of you while you are firing and YOU take the damage instead of the jerk. On one of their major updates they set it up so friendly fire did no damage to either plane. Just a waste of ammo. That was the way it was for the past several years, and it worked out well - the whining dropped to near zero.
Don't know if either one of these is possible in AH or not. Just throwing around ideas here.
