I absolutely believe that if they just stick through the one or two tough moment with the Dark Urge(and it literally is just one or two tough moments that are either forced or need dice rolls to avoid) they themselves would understand how good the origin is. That's my entire point: do not dismiss this character...you will not be forced into much more than the one or two tough situations and the payoff is amazing.
As someone who actually did abandon Dark Urge initially, I agree with the sentiment.
For me Dark Urge is quite amazing as a character with a very interesting story which I was going to roleplay either way even if it did not exist, but that one stupid camp scene almost entirely ruined the enjoyment of the character for me. Not because of what Dark Urge does that night, but the fact it does it without any of my choices mattering and I didn't like that at all. Because then I started thinking what if there are more situations in the future where I have no say in what happens and it keeps killing off side-stories or even companions which I'm very interested in exploring, at which point I just deleted my playthrough.
But then I started another Dark Urge and decided to just metagame that damn camp scene and been loving the character a lot since. That scene to me just entirely sends the wrong message from the one that was intended. And as it can be seen so it does to a lot of people, as many end up deleting their Dark Urge playthroughs in which they try their best to resist the urge.
