Really disagree on your late game air take. Restorer is solid as a comfy unit that allows you to scale an air win’s lead while continuously increasing your air to ground ability, but wailer and broadsword are great units regardless for being immediate dps dumps with massive hp. We don’t even need to go into the fact Cybran have the best strat.
I also absolutely do see a difference between asfs, the ability to stealth means that you can decide the first turn of engagement which, barring proper scaling, is the penultimate factor in deciding who wins an air fight. The only counter against it is proper spy plane screening ensuring enemy air cannot sneak up on you but that in turn creates weaknesses for cyb air to focus on. This is before even taking into account that if there is no spy plane coverage, cybran asfs can pop out of thin air and shoot your asfs while your asf did not have enough time to react and thus your air flies through them without doing any damage.
Does soul ripper suck? Sure, but Cybran still have the best strat and a broadsword equivalent t3 gunship. Finally, in a serious teamgame you don’t really want your air player to be responsible for washer/czar in current balance. Better to let some stagnant slot make it while air continues to secure their air win since the units cost nothing in terms of energy infrastructure. And for that security, Cybran is certainly one of the best.
