Not maxed and not necessarily cheating. I couldn't see the refinery, that would be a give-away for cheats, if they couldn't store enough oil for aircraft upgrades.
We do this - its not cheating, simply using the rules to our advantage. Our lowest ranked players are active but rarely take part in war. Just use them to make matchmaking a bit easier.
Firstly I couldn't see a post with this discussion but feel free to post a link if I missed it.
I'm ready to go Atomic and take advantage of the summer rush event.

I has this issue but now have anti air arranged so all approaches are covered. Not been attacked since. I fluctuate medals from 600 to 1600 and not been attacked yet. That said, I now have 4 maxed out ant air in global age, so it's a big benefit.
