Guys that is why you don't use the C stick for movement. Use the D-pad unless you need an angle movement then use the c stick. Also the c stick was not made for excessive pressure. You don't need to use a lot of pressure to use the c stick. It does not take much to move it around. Also don't push on the edge of the stick to move it. Put your thumb in the center and move it around that way. If you are Playing X/Y that is probably fine to do but not for smash because of all the movements.
