World bosses should not be available while the server has severe technical issues like last night with the login server being down.
When that is said, it is indeed debateable to despawn a boss at 40% HP.
This decision should have been made earlier by the GM team.
IN EITHER WAY you guys had a fair chance to take down Azuregos after it was respawned and login server was back up.
But as usual we won due to our coordination being at a higher level compared to yours.
Keep spreading salt - it makes my day even better.
Have a great weekend and see you next time in BRM
