coming back to what i said first.
it is likely that not all Dracthyr are created with the same amount of powers.
Also being among other races might spark different motivations.
Having claws, wings and other stuff does nothing if you might have never used them before.
Worgen also can’t use their teeth or claws.
again I’m not saying they need other classes from the start. but along the lines of the story they might get some.
