6 - Hes not too hard to use that you need to learn so much before you can start playing well against others. FRKZ and Bumpers are a small part of his game and using them comes with experience. Needless to say they are not needed at all to win so that is why I didn't rate him too high in difficulty. I will say I am still learning new things with him everyday and that is partially why I have not bothered to pick up another character.
Just yesterday did I start to get the hang of 5C (knocks out of air), 2C OTG, 623B. Before I was going into 6D too quickly and it would not combo leading into a bad oki situation. Anyways is there more I can get off that situation or is the 2c - 623b the best I can get?
