What I wish they had was support for videos in mods. I've thought about messing around with trying to hard mod a scene or character myself to add the functionality. I think some live 2d vids could go a long way in this game.
It's obvious the dev realizes that there is a problem with the amount of visual content because a lot of their dev time has went to fleshing out older fights. Like slime girl, alraune, minotaur, imp, mika, and some others; all have more scenes for their stances than they did a year ago.
