Nothing about the character is convenient. While awake he’s useless in a stand battle, or most situations. While asleep his stand is as likely to attack friends as it is foes. He’s designed to be challenging to play and interact with intentionally. Taking away my control over when he’s in which state is literally taking away the [i]only[/i] control I have outside of specifically how ES tries to wreck everyone’s day. At that point you may as well make him a NPC and cut out the middle man.
