I am concerned that the scaling down of action point economy will no longer allow the proper resolution to move strategically as well as cast, while stacking fractional turn AP. The depth of combat in DOS1 came from making tough choices about very small movements, and deciding whether to move one step and stun an opponent, or move none and heal an ally. The entirety of the strategic analysis wouldn't have been possible without a high resolution (in action points) of any sequence of moves in a given battle.
Any mathematicians want to go ahead and take some guesses at how the loss of fractional recombinations across a few turns will effect the complexity of battles?
