Here is how I see it, CaS it is not the optimal reason why you're playing a fighting game, but there is no reason why people shouldn't, play a game that immerse you in some way or another.
SC V CaS was pretty complete to be honest, I don't think adding facial sliders to edit the features would be a good call, at most I would ask for them to fix the layering problem, the high heel problem(Can't equip sock properly with the high heel item) and add a asymmetrical choice for gloves and shoes. Otherwise it is a pretty good mode and re-using assets wouldn't be a issue either.
In general, SC will never get the funding of Tekken, so while I hope they polish the hair (Which doesn't look great in Tekken 7 but much more serviceable) and models a little bit (higher polygon count, as I really don't have a issue with the less realistic style they go in general) . I won't be mad if they don't. The game does look good in motion and only when you stop (which in a fighting game is not much at all) and opinions on it looks so far have been really positive from people who saw it "live".
I'm not saying that there is no graphical issues, but I would like to see the game while playing before pass 100% of judgment, while not necessarily related, for sake of argument, the JP Taki trailer (official one) shows that Taki doesn't disappear completely after she does the projectile attack in her SCh and in fact moves forward.
All that said, I will say it again, I will hold up until the release, because like SCV and SCIV looked rough on development, it is possible this is the case here too.
