Wavedashing and L cancels... hard?
...OK then.
Anyways, I hate charge moves with a passion, but in Kof I have some difficulties with the following set of two inputs (alone they're easy but together they're evil)
Forwards shoryken motion->Quarter circle backwards to half circle forwards. I can do it on the right side of the screen but I always. screw. up. on the left side.
Also double half circle motions are annoying on the pad, which I learned thanks to KoF, hard to pick up you're finger after the first one and not drag it along the pad, that takes memorization, but it's not too bad.
Charge moves are the worse however.
