I just noticed this yesterday and it's kind of odd. Normally (not every time) I queue for a specific dungeon ("specific" meaning I chose the dungeon; doesn't matter what I chose), it also checks Spindleclutch I. I don't know if it has anything to do with the queue update?
FGI had some changes done at the War Chief. His adds will do a charged attack and an aoe. Even upon death (while laying there), their aoe AND charging animation will remain. Bonus: if you could pull the chest to the right of the closed door (before he died) that is trapped in cobwebs so it could actually be looted I'd appreciate it.
