In the gaming circles I'm in - the Dark Urge character 100% would need a warning. I think the biggest piece of information is that it is "not for the faint of heart" and that anyone who poses it as Tav+ or how larian intended to play is someone who doesn't exist in the fandom portions of the player base. It's naive and uninformed.

It 100% needs a warning, otherwise there will be as much uproar about it as Astarion's racism towards the Gur.
