Again, careful with "fixing" too much AI behaviour. It might result in the AI planes never getting a chance to heal, and thus make them easy pickings if you jump in a bunch of interceptors or start doing bombing missions of your own (and they can't intercept because they're too weak).
The current behaviour sounds okay. It's not broken, it's just conservative.
I just want to point out that this "unofficial patch" breaks the AI use of bombers:

That's the problem with trying to fix things that aren't really broken. You risk making things worse.
(Okay, I'm small and petty for pointing this out again. But hopefully, it will remind Solver to stick to the basics with his patch. If he's still working on it, that is.)
