Get rid of war levels, period. Give the security council some teeth so the player base can punish/prevent noob bashing, gang rape etc. A limit on the number of one fed that can be in the sc at one time to prevent 'fixing' sc votes.
It used to work fine, except a few bleated about being picked on. Why would it be any different now?
Ok, I know it wont happen. But does anyone really believe that just because someone remains at WL 3 or below, they aren't a war experienced player, no, I think not. Take Wendy, or Laguna, or even myself for instance.
And I dont reckon it's right to force my GR empire, which is basically the only place I make money because I have kept it unassailable, should be made to incur defense costs because of increasing WLs game wide. Maybe if the game sees 50T of military, then fair enough, up my war level, but if I have no military it doesnt matter how experienced I am.
