Vorcha do have a little bit with them as they can actually be educated to be civilized but have little time for that given Cats can live longer than them.
Yeah, there are a few races that kinda wished had been possible squad mates so you could get further in-depth about them. Except for Batarians, nearly everything about them is "Boy she sure do love being dicks and slavery".
There is the case that Elcor can chose not to add in the Adjectives etc. There is actually a example of it in 3 (Essentially you give one some really bad news, and its a minor detail they don't add it like they normally do to both show they can, and show how they are feeling without using it)
Misleadingly, I did not choose to have to limit descriptions of reactions in conversation, It was due to the undeniable fact that the Elcor are the most relaxed of the council races. Indignantly, My race should have been an option for crew mates on the normal, or at the very least our homeworlds...
Id be up for this, would likely focus on 1 or 2 characters so i can give them more focus and not get overwhelmed/watered down.
Ideas for characters are FF14 Zenos, Type-Moon Barghest, SF6 Juri or Arcane Jinx
