Yes, playing another persona user is out of the question for now.<br/><br/>It's off limits because the character's awareness has already advanced further than I wanted for this stage of the game. If anything, I'd allow everyone to play an NPC like a teacher (which I suggested before) or a fellow student (like HIkari is). Otherwise, other persona users are off limits because 1) I want to give people who want to join the game a shot at having an arcana 2) IF our enemy is human they may need an arcana.
