i actually agree that this game needs a proper dwarf.
I like to lean into tropes sometimes.

There should be some character sthat do that. a stout dwarf to rely on. an annoyingly smug elf (we already have that, but not in that way)
Something along those lines.
STout is something i wouldnt call any of the current companions. I think they overall need some testosterone.
A dependable Bro type of character would be a nice start.
Perhaps a woman thats a bit more womanly would also be nice, i guess otherwise well have to make due with Shadowheart
