Skirmish/balance feedback
Bomber Balloons are still slightly overpowered - for one thing, being siege units they can chase tanks, their bombs home on targets (so that Hunters always get hit even if they moved out of range after bomb was launched).
On the Bomber balloons, I think the issue is you have to make them more desirable than devastators because they cost more. So they should be faster than devastators and have less weaknesses. Plus they do get shredded by fighters.
I would make the balloons less resistant to dragon attacks, slightly slower, and decrease the blast radius a bit.
Far as friendly fire goes, how often are your troops really in a position to get hit by it? I think FF is negligible for the most part in the game.
