http://pastats.com/chart?gameId=244398 It's pretty obvious that air has some issues, and this game makes it extremely easy to figure out. Fighter HP needs to be reduced and T1 AA including spinners need to be buffed and/or target bombers.
If you do both you overnerf fighters, don't give Uber any ideas, Uber is trigger happy with overnerfing things.
Yes spinners need to give bombers priority and vice versa. Units need to prioritize based on threat level.
