I'd like to get my attack stats up higher towards my defense stats. Right now I'm at 167k/226k. It seems like every time I start adding high attack units or get a boost building upgraded my defense stats get a big boost and my attack stats rise hardly at all. Would like some advice on getting my attack stat raised.
Composite factory level 10.
Infirmary level 6 on its way to 7.
Air hangar level 6. Was going to be my next upgrade.
Water boost level 5.
