...all this stems from the simple fact that SE doesn't seem to want any sort of responsibility in this question. All they should do is pick a side: either put it down that the Duty Finder is random and anyone going there is to accept whatever situation they find themselves in, or that nobody's obligated to go through with anything in any dungeon. Former would abolish the "different playstyle" nonsense, obviously; in the case of the latter, they should just not punish people abandoning duty. That's it. But instead, we just have the doors open on both sides, so we're neither in, nor out. It's obviously not been good for so long it's baffling they still won't change that (lack of) policy. :/
