A lot for people agree with a lot of what you're pointing out. Many new players are held back from trying Dark Urge because of how incomplete the Dark Urge story feels at times. And a lot of players who do engage with the Origin character express disappointment with it being incomplete as you said.
With everything Larian is adding with Patch 8, and the fact that it's supposed to be the last Patch, I don't know how likely it is that any of our feedback will be heard, but I'll add my voice to yours nonetheless.
Lastly, I would also suggest they give Dark Urges Background: Haunted One, the option to choose the two proficiencies the class gives. If we can choose the Dark Urge's race, appearance, and class, it makes sense to be able to choose the proficiencies as well. Race, appearance and class would mean every Dark Urge would have different personal backstories, upbringongs and life experiences to each other, making the choice of proficiencies make sense. Maybe have the Background give a special condition or item which allows the choice of any two proficiencies at the start of the game?
