I personally like the time its taking for maps to roll over, at least untill it reaches the point where the fighting becomes stagnant.
And, IMO, the nuke gets a giant 'hell no you tard'. I'm fine with the bomber, just so long as people can take either max ord or max fuel/defensive armament, not both. Oh, and only have them enabled at 1/15 of the bases, scatered evenly through out the map.
