I haven't found that to be the case at all. Our party members are panicking and have big egos, but that's normal for adventurers in this world, and three of them happen to have dark backgrounds. Gale and Wyll seem to value treating others nicely and doing the "right" thing. I found most of the tieflings and several of the druids in that druid enclave to be nice and good.

I'm seeing this same post pop up a lot, and I don't really understand why -- the NPCs are definitely not entirely rude. And our party members are freaked out of their minds, along with having very strong personalities, which makes sense. What's the problem?
