1v1 most are pretty punishable, until you get one that turtles and waits for parries. They're working on a way to nerf him without destroying him completely.
Their unblockables are timed really weird for parries but you can parry the charge up heavy and other attacks, kick is an easy dodge 1v1.
The major problem with him is in 4v4. 2 average players with cents on a team can be overpowering against a good team of more skilled players.
Everything else csn be learned in 1v1, his punish is pretty powerful though so use quick attacks and don't get grabbed.
