Had a run like that in 67 dungeon. just like Heavensward, SB dungeons have that cut off point where stuff starts to hit really freaking hard. bardams mettle and onward. And it even continues somewhere at certain points in 70 dungeons. The game is not going anywhere there is really no need to rush or be rude to the tanks who could simply just STOP queuing for DF pugs for good and stick with their fc. They don't really need us but we need them, unless you have a tank of your own, which most don't.

Chill out, the game will still be here tomorrow and probably another half decade from now.
