At first thought, this idea seems nice, but the action points were quite usefull for balancing actions, especially actions that are supposed to take multiple turns to complete (building different types of buildings for example).
On the other hand, it will make skills like: your default stance is now attack/fortify/etc more usefull. With the old system you would be using 1 action point for moving, one of something specific, and the other to alter your battle stance, now you will actually have to choose: alter your battle stance, or move.
Few questions:
What to do with the fast travel, will it stay the same?
It feels a little unbalanced now: water, fire and darkness fast travel options are quite open, while light can only use one route?
For example, you could use the following for light: Stallion: when moving those times in one turn, you can move up to three hexes.
And, take a look at this 'map':
Lets say a fire player (with default stance attack) moves between the two fire 'hexes' and a water player moves between the two water 'hexes', will they battle in the middle?
