Seems kind of pointless to me to ragequit over something like that, since you still have the two hour lockout from when you first entered the Diadem. All you're doing when you quit that early is entering it to start the time so you can't enter it again for two hours. I guess that's one way to get out of people asking if you want to join them for a run though, "Sorry, I can't because I'm on cooldown for ragequitting. Maybe in a couple of hours"......
