I think GB3 should have maxium level of of 75 for bb players, 70 for CV players and 60 for SS players, that way intermidate level players that are within in this level range (50-75) can have a more gradual transition from Blitz to Great Battle. That way the game is more inviting for newer players who just came out of Blitz yet are not ready to face the big boys.

Bomber whores are easy to deal with if you use AA or fighters. Or if your team supports you with AA/fighters.
