Potentially hot take: Gun SPAA defending bases should make a return 13.0+
Put on your cope-glasses on *With decent rewards for destroying them*
Back a few years ago bases had two gun SPAA defending them and they were removed because it was dumb when you were just minding your own business and get slapped by a terminator AI Gepard that you didn't know was there. Now SPAA is less likely to target you if you don't have A2G weapons and most top tier fighting happens out of SPAA range anyway
We've now got GPS glide bombs, POI bombing, super guided missiles, ARMs so I see no reason why aircraft should still just be strapping themselves with bombs and flying in a straight line towards targets on a map. No thought behind sorties and no coordination between teammates just mindless zombing.
I could go on about how bases should actually as detailed as in NT with Ammo, Fuel and vehicle Depots but thats too much to ask for a forgotten mode
