I've been really looking forward to a Dio since I started playing YOMI and more so once I found Diavolo. But with this one, I am left wanting more, especially since you have characters like Broly, Colossus and Niflheim which are very well fleshed out characters. I think Dio really needs more diversity in his play. It feels like there's no reason to play Stand Off as you lose several moves which hurts your combo game, and Supers which all seem more versatile than his Stand Off supers. It would be nice if there were more Stand On and Stand Off moves in his kit to make combos more fun and less same-y. His lack of movement and defensive options is also really unhelpful. A lack of a roll makes his disadvantage state awful, which is not helped by the lack of a grab in his standard moveset, which is crushing. Also, no dash or super dash makes movement a chore.

That's all that I can think about really. I will obviously keep playing him, but it feels like he has less polish than your other mods.
