The only way to make this work would be to balance out ability scores...which they aren't right now.
Take dex vs strength for example. Dex gives you AC, reflex defense, initiative, and several good skills.
Strength gives a few skills and fort defense. If I have the ability to make my attacks depend on strength or dex, I am always going to choose dex.
