Your proposals seem geared towards making the AI attacks meaningful at lower AIP, which ruins a whole two other playstyles:
1) higher AIP, but still relevant
2) AIP, what's AIP?

To elaborate on this... I've had, personally, the most fun with AIP between 200 to 400, and rising a bit. Then lost repeatedly. Then found the low AIP route. Then won, bored out of my mind. Tried a few more options, like golems, spire, and so on, had some fun discovering new mechanics. Tried a few "harder games", but the low AIP route crushed fun into a hole. Resumed back into new mechanics and lower diff (7-8), and higher AIP. Funnier game, and I like discovering new features.
I'd rather have made the game harder, provide some challenge at the same time I would have discovered the new features, but the challenge it's providing is a test of my patience, not of my skills. That's what I did with X-Com EW, cranked-up the diff with starting with mechs. Had more fun than ever.
The design of AI war II is plagued with people's conflicting playstyles. Nothing can change ever because some guy's playstyle is gone. I don't know where the game is going with those idea in mind, but I don't think very far. What, 60, 80% or 90% of suggestions on the forum can't be done because it alter's some guy's playstyle. I understand that, but... from a design, from a "what could the game be" perspective... feels very limited to me. Where the game should allow the game to do stuff, I feel likes it constraints itself into not really resolving stuff that caused issues for years.
I deemed obvious that given that it's a sequel, it'll be a somewhat different game, and that some of the extremes, or that some of the parts that are known issues since the start of the game, would stop receiving whatever band-aid they got, and got "more real" solutions.
Like: low AIP route (I think that's the part of the game that has received the most band-aid over the years, CSG, deep strike counter attack, multiple reviews of energy mechanics, dire guardians, dire lairs...), like the AIP feature and the stalemate it causes. Like, the refleeting mechanic (slow, boring). Like, the fact that the game is soooo damn long is not an issue if most of that time wasn't waiting time. Other issues are around. These are the few that come to my mind now.
