Just to let you know, that is kinda really stupid that when you finish an instance (Garuda HM for example), he drops a loot, and you can "NEED" on it, and you have to wait the timer on roll to be down or you won't get it, and then you can't quit the instance.

To resume, the roll device is totally fucked up, when someone need, the greedy should be canceled ...

If you are in a instance, you have to wait till the role timer goes to 0 to leave instance. And if unfortunatly you "needed" and you leave instance you'll be totally fucked up ...
