They really should move AP to skills or something that people can dump into because as of right now it's a lose-lose situation for everyone.
You basically have to go con + other stat.
If it's on a skill you can then you can specialize much easier fitting various play styles.
That's my gut intuition anyways. Either make it so "Way of the X" reduces Y associated skills by Z/Z% AP or "Combat Knowledge" as a universal skill that increases your AP cap and "Combat Maneuvers" as something that increases your AP.
