Kind of funny when you think about it. Sonic is probably the most neglected third party character that's been in Smash (only got five seconds of SSE screentime in Brawl, arguably poorly balanced in Brawl, only one original song in Brawl, no original songs in Smash 4, only third party character to not be in a cinematic etc.) and even though the buffs in Smash 4 were enough to make people think of him as a top contender, he still gets almost entirely neglected in patches. Probably cause so few people play as him.
Oh well, can't complain. Smash 4 Sonic ended up being almost everything I could hope for him to be.
