Spar
 

In the waiting room, might I suggest to make it so when you say leave, it does not take you all the back to the main level, I might just be lazy but I don't like walking all the way back XD!

That's there so people in the spar don't just say leave to heal, then run right back inside and attack the person they were fighting again, also so people dont attack people who try to leave, and also so the door cannot be blocked by people. ^_^
