Eh, not really.
While I thought previous versions of Yoshi had dumb/silly stuff, I don't think I could say he's anything above average, and that's being generous. He's a really slow character with a not-so-good neutral.
He's got some things that are really good though:
- Dtilt (I think the whole tail being a hurtbox is weird, but at the same time I don't want to deal with a damn disjointed tail that essentially acts like a shine spike in some regards)
- Double Jump Land. It's especially good out of shield and anyone who actually still mains yoshi has no reason to do this. Down Smash, Fsmash, up tilt, and Down B out of shield are all amazing.
- DJC uair strings and he's also got an overall good combo game.
While I did think prior to 3.6 that Yoshi's grab needed a nerf, I still think he could have a couple of frames at the max range of his grabs that allow him to grab an aerial opponent (with a smaller grab bubble than the one at the start of the animation). It needs something other than what it has now. Given how slow the startup on 2/3 of his grabs are, it makes no sense that he can't even use them to punish a bad aerial approach. Even if you want to compare it to Link and Toon Link by saying that they can't grab people in the air except for the earlier half of their animation, that still kinda doesn't mean much considering they also still have good enough projectiles to help them in neutral and vs bad approaches (especially Toon Link, who not only has good projectiles, but he's really fast to boot).
Bad baiting and bad neutral + bad zoning with his projectile unless he's either on the ledge or his opponent is offstage (and most characters can still avoid them easily anyway).
I can see the direction they were going with PM 3.6 Yoshi. They obviously wanted him to be more like Melee Yoshi, but he really got no compensation for his nerfs whatsoever lmao. Not to mention he got nothing but nerfed. Not redesigned or anything like that, just nerfed. I feel like people want to believe Yoshi is godlike because hardly anyone plays him and they think he has some potential to be a top character, but as someone who's been fighting a consistent Yoshi main since 3.0, the character's just bad lol.
And no, Yoshi not being footstool-able during his double jump is not what I'd consider to be a big or major buff because Yoshi mains never had any business recovering that low in the first place.
