I'm intrigued to see just how much the modders will be able to do with DAI.
I am too. In a way, announcing that it would be almost impossible to mod was like waving a red flag at modders to challenge them. Hair mods, obviously, are the thing people want most universally, I think, and mods for the PJs (at least the color, I mean, honestly, rich color was evidence of status and wealth historically, not even peasants wore beige which is essentially undyed cloth - you can dye cloth with things as simple as onion skins or lichen. Even white is much higher status since it took a lot of work to keep white looking white.) A better range of hair colors would make me happier (like black that's consistently black and a more attractive blonde.)
I'd be thrilled with a f/f mod for Cass since that's the only feasible one of the four LIs I really like but are gated to my female dwarves. Cullen's isn't because he isn't adjusted for the different heights, which is an entirely different level of work to alter, and I feel that Solas's race gating and Dorian's gender gating is too intrinsic. Since Cass enjoys having female IQs flirt with her, I think the mod wouldn't be much change to her character.
