The fewer actions for me the better. My tabletop campaign takes 20 minutes per round. They are filled with people with long faces waiting for their turn as people take an action then a minor action then a minor action as a move action then an action point then an immediate action before ever getting to OA, and none of the minor actions are inconsiderate. Move and act, and possibly react. Clean and simple.
As it stands right now, hiding as anything other than an action is too powerful. Hiding is a defensive action, but grants the rogue offensive abilities. If you were to hide and attack each round, monsters go from being able to hit you 40% of the time to 7%, your ability to hit increases 19% and your ability to crit almost doubles, your average damage increases by at least 33% and to me theatrically does not make sense.
