You guys are probably right. I mean im far from being a Hazama pro lol. I tried it out in training mode and I realize I been canceling 5C into 2C after only one hit. I tried it with two hits and it does very little more damage. By very little im talking less then 100 points. Also if you use 5B you can still follow up with 4D~A > 4D~D. I'm sure there's more to it then I'm seeing though.
Also in alot of the vids I see (combo vids, pro matches, etc....)They usually if not always go into 2C after only one hit of 5C....
