No one enjoys clicking start, character, denied login, start character...

Try logging in for 5 minutes without getting pissed off. This isn't Square-EA's first MMO.

After the server says "full up bub, try again" it doesn't even give you the courtesy of going to your character screen and tosses you back to the start menu?

You don't kick afk players offline or seem to have a method to kick inactive players so whoever is online could not log for a week and you see no issue with this? My friend went to work while logged in and was still standing around in-game 8 hours later.

At least Blizzard forces you to log off their server after a set period of idle to prevent locking up server resources.
