I'm not sure that I understand your question. I had hovers in my main city in Indy but that was 3 years ago and my boosts, then, were nothing like what players can achieve now (which makes that experience dated). I currently have all of the available HAUs in my secondary city. It's now in PE where I battle mostly with AF Recon Raiders. With 1200 red attack and 1100 red defense they get me to 65 attrition without any losses. Beyond 65 I switch to 1 Turturret with 7 Rogues and can autobattle to 100 without losing the Turt. When I first got the OF units I manually battled to 150 (old GBG rules), burning up a lot of diamonds in the process, just to see how far I could get. I have Hovers but don't use them. The first strike capability of the Recons and the mortar ability of the Turts seem superior to the Hovers stealth. Lastly, with 1000 blue A/D I can get thru GE L5 easily.
