Well that's the thing, I don't quit
because I'm losing, I quit those matches because my controls weren't working.
My 3ds' R and X buttons can be a little finicky sometimes. They started to get kinda wonky during Shulk vs Dr. Mario, and got better during Mario vs Dr. Mario. It wasn't until the Mario vs Dr. Mario match that my controls started to work relatively well again.
Also, it's weird how you say I'm good with Luigi, but that Shulk needs work. I generally consider Luigi to be one of my worst mains, and Shulk to be one of my best.
Aside from all of those quit matches, all of the ones that we finished were good, yes.
Thank you for the matches as well.
