Wow good list with a lot of good ideas.
About Recover, I think this perk can be passive and restore as now 5% + 5% * (remained AP). You can restore 50% as now by skiping turn, or restore 10% after two attacks.
Not a bad idea. There’s a bunch of times you’re left with 1 or 2 APs you can’t use (either due to positioning or fatigue), and having them serve Recover would definitely synergize well with the perk.
