Say you're in Blue, finding the action nonexistant, the fights dull and boring, and you want to go to Orange. You may not want to bother leaving if orange's cap has kicked in, right?
But if you log out of Blue you may not get into Orange, and chances are you'll just log in disgust/despair.
How about a .sr-style tool (maybe ".cap"?) that simply replies: Blue: 150/250 Orange: 305/300
That way you won't have to log out.
This will NOT replace checking the arena if it's very close (waiting for that "1" to free up) because by the time you log out and back into the other arena it will be gone. It WILL be useful as a general idea of how crowded they are.
