I think for "letting the AI get past chokepoints", teaching the AI how to deep strike may be a good idea. Like, there would be a chance that fast-ish units, or units with properties that are good for raiding (FF immunity, grav immunity, tractor immunity, cloaking, etc) will try to go to another planet in (with a preference, but NOT absolutley so, towards human planets going closer to the homeworld or other valuable structure) upon first coming from a wave or from AI space to non-AI space.
With the upcoming nerf to gravity, this would be quite threatening. Imaging those raid, bomber, maybe cloak, maybe FF immune ships having a chance to ignore stuff on your chokepoint, and just head straight for the "next planet in". If they can make it, they would have a far better chance to take out valuable infrastructure (like energy collectors) that may help take out the chokepoint indirectly.
Again, this should be a chance. Many, if not most of the time they should just use the current, "general purpose" logic.
Also, possibly, the stuff that wouldn't fall under the "raid classification" described in the first paragraph could have a chance to do this too, but just much less so. So occasionally, you may see your a whole wave try to do this, instead of only part of it (if you are playing schitzo waves).
However, expansion on this discussion should probably go on a new thread.
