Somehow you don't know about NeatUnsou's Nu-13. Where the hell have you been?
First of all, it's not about the combos. The characters themselves feel wrong, they have bad vels, no hitstun decay, have many animations that are botched, and they somehow manage to slow down 1.0 with too many conflicting helpers. Ragna gave off huge debug flood last I tried him too but you can live past that. But, even just watching them you know a lot of stuff is wrong, and I haven't even played CS2 much in a long time at that point. And say what you will about Speedy (you know as well as I do you can say a lot), at least his things don't try to emulate the system and manage to come way off the mark.
EDIT: And why mostly Speedy's? At least he's taking an effort to learn and his Bang, while an incredibly mixed bag (decent ideas, execution all over the place (okay or terrible)) is already better than anything Kal has made. Mu was my limit.
