The way the arena is set up now, if you sit and watch in the arena select screen sometime. Is that one arena is full, or nearly so. If the other arena is gaining numbers then limits will go up. Problem starts if blue for example starts dropping people and orange is full or nearly so.
It sets up almost like a revolving door. Orange Cap is 320 with 314 on, cap goes up, people go into orange. Cap is now 360 with 330 on. People leave blue, numbers drop in blue. Then the door revolves and it goes back to the previous cap. So now we are capped at 320 with 330 on.
If the numbers come BACK into blue because they are stuck getting into orange caps will swing back up, the door will revolve again and you can get back in. Chances are it will do it inside of 5 minutes.
The exception is as prime time US slides closer to midnight and numbers start falling the door may not reopen for some time.
But most of the time if you'll just sit in the lobby and wait a couple. Go fetch a beer, pat the kids, kiss the wife, kick the dog whatever. You can get back into where you want.
