Nobody can force me to spend my time a specific way... But here we are.
You call it garbage game play, I call it effective use of my exceedingly rare entertainment time and $15 subscription.
Give them airspawns and revoke it's use after bailing from a non-player damaged aircraft. Now they may be more inclined to RTB if it's half the time required...
I dunno what the answer is, but it's not telling other players what they can and cannot do in a game that has mechanics to allow for said action.
