It is in my opinion that the server may have several corruption issues, particularly with world bosses. In this event de-spawning a boss in the middle of a fight to exercise fairness is not the way to keep players happy. This affects alot of people on this server and discourages players to even consider world bosses and progression. It is in my understanding that this was a pure judgement call of one person.
I would like to see a detailed report of the issues (login and Azuregos) and reasoning behind the de-spawn.
