Lol he was stronger with his game in CS2/EX, other people just closed the gap in skill. All you niggas (And myself) sucked ass in CT/CS1, that's why he seemed so amazing in those games in comparison.
Misturu v. Yukiko has to be 6/4 Mitsuru since Yukiko is squishy and she probably is one of the better characters at just breaking personas, but Yukiko can definitely play well enough to keep Mitsuru old and hold her in pressure for long periods of time if done right.
