The point is this one, those players where in a corner of the map not contributing anything to the team while the rest were battling the capture points for the sake of the team and the match.

The game should encourage team play and objective cooperation, not the other way around.
This could be solved easily if the planes fly away out of the map once their CV is destroyed
