Yeah, rolling a Drow seems to be about the only thing right now if you want to feel 'special' since the custom MC doesn't have any special quirks or story plots unique to them. Even Gith and Tieflings don't feel that unique since Lae'Zel is already one (funnily enough, probably the most 'normal' out of all the party members), and she, unlike the custom MC gets a bunch of unique dialogues and reactions etc thanks to her storyline of tracking down the creche. And there are dozens of Tieflings in the game, it seems, so being a demon/devilspawn doesn't exactly feel that unique....plus we'll be competing with 'spits in Baphomet's eye' Karlach when she's playable.
Some of the party members definitely could stand with a toning down of their more outlandish feats. Gale could have been an arrogant wizard who overstepped and is paying the price rather than this archmage he's made out to be. The Karlach going toe-to-toe with demon lords stuff specifically is just way too out there for me. I can pass off Wyll's stuff as being self-promotion/braggadocio, and I think Shadowheart and Lae'zel work fine. Not sure about Asterion. 'vampire spawn who gets infected with a magical mind flayer parasite that protects him from the sun' is a bit...convenient. At least he wasn't made a full vampire, but it's still not a concept I would have gone with.
I'm hoping we get to see some non-origins party members in the full game that aren't as extreme, or that some of the OTT stuff gets toned down a bit down the line.
