I have always felt it a little jarring when I am in a party that has characters ranging from a talking bird to a centaur with nary a traditional humanoid or human in between. It really feels like a circus troupe rather than a party of adventurers. I find that to be especially the case when none (or hardly any) of the Player Characters are native to the region or are even completely unique beings. I can't specifically say that it's because I prefer a human-centric approach because I would have no problem with a majority Dwarf party, Elf party, or Gnoll party.
Does anyone else have this problem or is it just me? How can I move past it? Are there ways I can frame things in my mind to make it easier to get on with?
I used to feel this way too. If it helps, I justified it to myself by saying, they’re adventurers. They’re already a rare bunch just by the nature of being the type of people willing to brave the dangers of the dungeon for fame and glory, or risk their lives for the sake of others. So, what’s the big deal if they also happen to be racially (or I guess specially) eclectic or 75% spellcasters in an otherwise low-magic world, or whatever. I even kind of incorporated it into my mental framework of the milieu that adventurers have a reputation for being so circus-troupe-like. There are probably plenty of “a tiefling, a drow, a dragonborn, and an orc walk into a bar” jokes about it.
It’s kind of relatable in a way, if you belong to any obscure or outcast subculture. At least in my experience as an LGBTQ person, we societal outcasts tend to be drawn to each other. The rest of society pushes us to the margins, and we end up finding each other, because we all share that common experience of not fitting in with the rest of our peers. So, we band together for community and solidarity, and we form little bands of weirdos and freaks. Who among us hasn’t been on some outing with their friends and caught a stray “is the circus in town?”
Framed that way, it doesn’t seem so strange to me that adventuring parties would be similarly conspicuous within common society. Indeed, perhaps it is this very ostracization that drives them to become adventurers in the first place. The goblins, kobolds, Tabaxi, and Shadar-Kai have a hard time finding honest work because nobody trusts them, so they end up taking on dangerous mercenary work to make their way in the world, and through that work end up meeting others who are there for similar reasons, and decide to look for the next job together.
