One thing that I've been noticing is that it's impossible to do space combat. Avengers have zero counter and trying to do anything in space usually ends up with a cats game. There really needs to be some more space combat units or something to improve space combat so you can actually do some damage.
Anchors are cost-efficient against avengers, also umbrellas will help secure an orbital zone to mass up orbital units
You can do damage with the ssx and anchors already If you want to do more damage use nukes or send your armies as they are your main fire power... Orbital is there to support your troops As it is the layer that is always available to every planet ... air is the second most available with the likely exception of gas giants and used for quick mobile fire support ... Adding too many heavy damage or naval like units to orbital would make the other layers be less usefull ... If i can do everything i can do on surface in orbital aswell why build any mobile surfaceunits except anti orbital deffenses when orbital is sooooo much more flexible? And again you can do dmg with the ssx and anchor already I personaly dont see a reason to add a orbital antiorbital bomber or antiground naval like unit because you have the options for that already
