Scenario: You log in to AHII and you click on online, the arena list pops up and you see this:
Green 10/170
Purple 40/170
Orange 449/400
Blue 150/300
Then you type in the old .sr/.f command to see your squadmates, or buddies, or favorite bad guy in Orange.
Then you hit quit, log back in, but accidently hit the offline arena (as you mutter obsenities to yourself). Quit log back in again to find:
Green 12/170
Purple 42/170
Orange 446/400
Blue 153/300
And you continue this process until the arena you want to be in has space. So here is my proposal, a refresh button that you click and update the current arena numbers.
