Here are some of my personal thoughts.
Similar to @Turbanator's suggestion, we could rework the transport points to a more generalised "pilot points". Pilots gain points for transporting players to the AO, stocking the FOB and eliminating targets from any CAS aircraft. I would structure the points something like; 0.5 for lightly armoured vehicles, 1 for heavily armoured vehicles, 1 for helicopters, 1.5 jets.
This would provide those more inclined to the CAS role an opportunity to increase their points from the CAS seat, rather than ferrying players back and forth to the AO. If you're a decent pilot, you could attain 20-30 points even with a Buzzard very quickly. The current arrangement isn't too bad, but I can appreciate where y'all coming from.
Something that could also be tweaked perhaps is how high you have to sit on the leaderboard to get the newer CAS aircraft. A little nerf may go a long way.
