I've seen a very nice discussion in this post and a previous one.
Looks like the consensus is:
Bombers are too good vs Caps & Fighters, and the main solution is:
Nerf Bombers agility
Buff Fighters weaps
I suggest to do only one of them, otherwise other balances in the game may suffer.
I'd like to buff the fighters since it would be more RP-friendly. After all this is an RP server.
