imo roy is mostly easy to use because he's quick and hits strongest with hitboxes that are closest to the hilt and his OOS options like upb. also roy has a chaingrab
his fsmash is ridiculously strong too
i don't know too much about roy since i don't use him often but he's quite annoying to deal w/ in for glory
is it bad i'm only good at peach and falco
and i'm trying to learn kirby
i'm only fairly good at jigglypuff and peach; specializing in a couple characters is nothing to be sad about. it can allow you to have a more intimate knowledge about that character
