It's been a bit frustrating for me when I'm trying to get into the Arena or start a battle when half of the time the screen doesn't ever finish loading up or the connection times out forcing me to log out and log back in. Sometimes it accuses me of a double-login so I have to wait a good 10mins before I can get back in.
Each time I would think about how nice it would be to have a button to refresh the connection or have it try reconnect when it takes too long for the loading screen to finish it's stuff.
