I like it.  I rarely play lower ranked players so I was always suggested a ranking range for a created game.  For instance I would create with Range Attack and players in top 50 only.  We could also have players 150 and lower for Editor.

     
Yes, I've thought about that too. So was the possibility that can be selected or not. Also that a player can play in lower divisions if he want.
 
The divisions can be made so that large group of players are to minimize this (commentary).
 
However, if you put a challenge with "division" and no one plays, you can always remove the restriction (as with "registered").
 
The other side of the coin (frustrating) is that sometimes one wants to play games with top players and bind to the game players who play "game crazy." I personally do not give me anything these games. Moreover, if a low ranking player loses, his ranking remained the same. However, a player with a high ranking loss, of this type (dull game crazy), involves many negative points.
 
     
Sometimes, the improvements have to try to see if they work. If do not work, nothing happens, turns back.
 
But, if we are missing something by not trying?
