As a general rule of thumb, the more recently added a class or race is, the more specific options and dialogues it will have.

Duergars from Grymforge didnt even tryed to enslave my Deep Gnome ...

Feels kinda disapointing. :-/
Like playing a Drow, killing whole Aradin Group by my own hands ... and yet being welcomed in Druid Groove as a Hero. :-/
