But in TES3 it made no sense to use any other than the 'best attack' on each weapon. In TES2 the damage and hit chance was different to each strike, so it had a tactical approach, even if not major.
That's not a problem with the combat system, but with the weapon values. Its the same issue with spears. Spears svcked not because the skill was inherently flawed, or because spears aren't fun, its because the spears that the weapon designers made were weak and silly. Its not a problem with the system, but with the items within that system.
Having said that, moving determining strikes didn't work so well because you move around a lot in many different directions, but you don't want certain strikes to happen. Oblivion's 'push and hold' system worked better in this aspect, because I could move any direction and still do my power attacks like I wanted, instead of doing slashes just because I'm moving left or right.
