Can't drop the idea about regenerating action points while being motionless, it's impossible because you aren't regenerating when running in either case your trying to present, your trying to invent a new wheel. Furthermore, it doesn't work that way in practice like your example, trading action points is undeniable in combat and a character with higher action points will be able to move farther whilst accumulating the same action point amount to act as a character with lower who won't be able to travel the same distance to act the same time, that's how the speed is managed in real time combat,
combat, take notice that outside of it it's pointless how much faster you run, and that's the situation your presenting. Running in RT combat means that each second you are loosing action points witch are regenerated by the opponent, none has wasted action points? "The turn" hasn't begun, yet, until then it's irrelevant just like in original fallout games where real time outside of combat didn't grant you any actual movement speed, like in Fallout Tactics it was managed just like it's on 2238. The concept is solid, you just want to add another factor witch in my opinion isn't necessary, you want to amplify the existing advantage, don't see how it helps with balance, nor worth the effort. Characters with high action points have enough advantage and in practice most builds out there have almost the same amount of action points give or take. Snipers was the reason why we started to talk, and snipers aren't imbalanced or weak because they aren't able to take full potential of agility like you think it should be.
and imagine that you constantly regenerate AP, and moving consumes it (as it should).
Impossible like i said, unless ... regeneration speed exceeds the speed it decreases upon running, you get an effect like this. It will result either in decrease/increase of AP while moving depending on how fast it increases/decreases, can increase and decrease at the same time, it will give one of those effects and not both or none effect at all, middle ground. Currently it's absolute zero, you are regenerating action points at the same speed it decreases while running, so basically you are not regenerating action points while moving at all and not loosing them either.
