Some people do dungeons but don't enjoy them and want to get out of there as soon as they can. I will never uderstand them but eh.

I've been farming a lot of dungeons lately for stuff to desynth and have come across a lot of tanks. Most of them aren't really good at speedrunning but want to do it anyway, very few are good at them, and a bunch doesn't speedrun at all. Personally I just adapt to whatever the tank is comfortable with, I don't mind either way, but I've seen a lot more people getting angry at the tank for not picking up enough than the opposite. But if they turn nasty, I just initiate a vote kick and they are dismissed pretty quickly.
