You may be right.
There are many ways AI could be further leveraged in AH. Some more aggressive than others. It is also possible to tie it to player numbers.
Some past ideas like defensive patrols operating a certain distance from a base is really just an extension of the same justification and concept as automated field ack.
Other ideas such as a perk purchased bomber mission against a strat could be tweaked to be no more over-used than you see 262'a now. They might form a good nucleus for other human bombers to form on and human fighters to join on and escort and enemy human fighters to intercept.
Both of those possibilities are either fairly constrained or player initiated and directed. The careful use of AI augmentation doesn't necessarily have to mean completely free roaming AI across the map.
But yeah, those are all thing Hitech will decide.
