Auto attack could be implemented in a way that it doesn't really interrupt the way the game currently works. It's quite simple really. First: allow the players to decide what their auto attack action will be. Second: allow the players to toggle the auto-fire of this attack on and off. Third: auto-attacks are only initiated when the stamina bar is at 100%. Fourth: Add a delay value to all weapons, but not like FFXI. This delay value can be multiplied by a base-value per action to determine how much stamina the action consumes. This way we won't have issues where a dagger uses just as much stamina to attack with as a spear does. Also, this will add more depth to weapon selection, which I think is a good thing.
