Tell you what getting the GameCube adapter up and running, has made a notice difference online. Used a usb splitter so I have enough room at the back for when the lan adapter arrives. Rumble and pad both work fine on one port.
Never liked using the GameCube controller for anything, I find it too small for my hands. Using the Wii U Pro controller is perfect for me on Smash but I might try the GameCube controller if I can find it
