First time playing after a long while, in a beginner dungeon no less, and these people are already unwelcoming as hell. Some people just create way too much stress for this kind of thing.
I'd say it was just a bad run of luck. Most of the early dungeons i've had to rerun with pugilist, people have been pretty even tempered, especially for new people.
Then again, there shouldnt be much that can go wrong in beginner dungeons.
