You can't cancel 22C into anything; it just recovers really fast. You can actually use it as a whiff cancel. It's kind of ghetto, since it's two frames slower than 5A and has no whiff chain options, but it also carries no reverse beat penalty.
Probably worth using more on opponents you think you can outplay meta-wise, as:
- They are more likely to push buttons.
- When they do push something, they are more likely to win, since they have frame advantage.
- However, you still have implied initiative.
- Your damage output also gets a good boost since there is no RB penalty.
22C is a really good fake, the problem is that the moves its faking are not very good. 214B is a good special but has little application in spots where you would be using 22C to mix up. 22A and B have limited but non-zero application (for example, you can use 22A to beat backdashes and 22B to beat someone trying to anti-air an IAD). 214A and 214C just suck.
For what it's worth, Veteru has admit to me that he thinks he doesn't use 214B or 236A enough.
