Cyromancer should be more plus and have more range on his variation-specific normals, SZ is a tankish character it would be more in line with his design. Leave the RC cancel stuff for characters that are supposed to be fast like Roo Kang and Cage.
Yeah there's no way cryo will ever get cancels although SZ is not a slow character as you portray him.
As for his strings being plus that is not going to happen either, making his universal strings plus is out of the question because that would be a major buff to all the variations and SZ is just too OP as it is
What remains are his variation specific strings like 111, f12, f122 and f42 grab.
f42 grab is out of the question when discussing strings that should be plus it should stay neutral or be +2 or +3, why? because making that string highly plus would be really OP. Cryo making u guess overhead/low/ every time he lands a f42 grab and if you guess wrong he gets to do it again and again without you having the option to armor wake because the string is a standing reset.
That only leaves 111, f12 and f122 pointless strings that could really use some buffing if they are going to be used for pressure.
As for Cryo's specials... Air hammer is useless right now I doubt that anyone has given any thought how this could have any advantage, his regular hammer overhead has 36 frames start up and his EX hammer has 28 LOL.
If Cryo is to get better someone from NRS needs to improve something on those moves.
