I'll come back with my proposed changes for Cryo in a bit. He doesn't need much, just a bit of shuffling to do his role. I love the nuetral standing reset, it's one of the most unique and awesome things about him. No armoured wake ups, no counter 50/50 into punishes/whatever, nope just high damage strings straight back into the neutral game, but in perfect spacing for a D4 and a B2, as well as arguably the best backdash in the game to support it.
The problem is his lack of a couple of footsie tools, and this is the footsies variation. His improved uppercut is good news, but his ex-hammer is shitty. It's not worth the meter in a successful string as far as damage goes, it can't be used as a mix-up after a blocked low opener because it's so easy to Fuzzy, but that's fine because it's role is the nuetral game (right where he needs it), which it almost does well, slow armoring through even other armours and launching into combo. However, it's so completely free to jumping and cross ups, and anyone with multi hitting armor like Kenshi can really mess it up. So I propose one thing, make the Hammer multi-hit the whole way through its swing animation, solving both problems at once. Get rid of Ice Burst which is now absolutely useless, and change it to something else to help him in his role. Call me wishful but his Ice Puddle would be dope. Tombstone drop teleport could be alright as well. Some sort of frozen projectile like Hammer or Dagger could be useful for decent chip as well.
