Dair is a little too potent imo, but Yoshi is still somewhat under the radar so shush. I honestly think the main thing in need of tweaking for Yoshi is his egg roll. Decent shield stun, good priority, low lag, good setups. There's just so much good for a move with fairly small commitment, but still it's not broken.Flutter jump shuffle (Down air for Yoshi) is pretty broken, even in Smash 4 if it manages to land, it's a free 32% into an up smash.
Down B is broken though lol, soooooo gudd
