This is in response to the fourth section, Troubleshooting.
Instead of changing my button setup, I did something completely different: I changed the way how I held the controller. The only thing I really did was move my index finger to the jump button, so that my thumb could easily access the B button and the C-stick. I've been conditioned to doing this for awhile, though, and it's not that hard to get used to it. If you apply the C-stick to many of your moves, this may also help you a lot more.
