This is me on For Glory. (Well technically it's "online", but I never do anything else so. Don't ask me why the stats are out of whack for this.) I pseudorandomly hop between the characters in the top two rows of my competency chart and occassionaly some in the third row. If I stayed with mains I'd probably have a better record, but eh.
Aggregate stats ignored for characters with less than 5 battles.

Oddly enough, I've never played online in SSB4-U. Not really sure why.
