when some one has to leave the computer for a few minutes say up to 30 minutes.
why not add a small button at the bottom with a book in it and when clicked on the player sits down and reads a book. after 30 minutes the player is then removed from the game. this would end all the dizzy wizards who are spinning in a circle. and the inactivity would cut down on the lag in game as the wizards are moving very little at all.
then the commons would have a lot of studious wizards there.
