Scribe, you clearly play a different game than I.
I suppose so. I would say a session at a camp, in a tavern, on the trail, where people really explore their characters, and how they relate to each other is great.
I mean in my youth, I did a lot of manual labor. You have a lot of time (while digging, or loading, or carrying) to shoot the breeze.
If you haven't had opportunity to have discussions like that, I would be surprised.
Now are their class concepts which are clearly opposite? Sure, you picked a good one, but that's a bit of a goal post shift don't you think?
Bringing this back again to the topic.
If I'm in a party with a Lizard person, who looks at me as potential food, who doesn't share the same emotional World view, why can't that be discussed at the table?
I'm pretty sure Tas never plucked Flints axe out of his hand mid swing because he just HAD to steal it.
The game is not a straight jacket. It simply isn't.
Your class, your race, your alignment, your stats! 5e is SO forgiving and loose, you are not required to play within some straight jacket framework.
