I feel like Yoshi is a lot better, but I am slightly disappointed that his throw really couldn't be made better. By overall design they just aren't built to possibly set up anything ever. All that could be done was more damage really, despite my best attempts... I do think the extra pummel damage (as opposed to more damage on each throw) was a good call. Making Yoshi biased against fighting high-% opponents really emphasizes that he is then endurance character.
Edit: I think I realize the source of my apprehension about Yoshi. Although the ultimate goal of these changes is to balance matchups at high-level play, many of them have the happy side-effect of making the characters easier to pick-up or making existing playstyles immediately superior. Two of Yoshi's biggest changes, Egg Braking and the fair pound, do not have these advantages. No one is gonna say "man, I can't wait to play Yoshi because of Egg Braking!" like they might say about Link's arrows.
However, the point of this is balance, and not to market low-tier characters or increase their popularity. Yoshi will probably always be a niche character, and not much will change that.
Double Edit: I never mentioned this I don't think...
After early on when Yoshi mains questioned the utility of fair pound, I asked JGALT, a Yoshi main I test with, about it. He gave a strong defense of it, saying that it was very useful for Yoshi to have a powerful punishment tool in his back pocket, even if it was obscure and risky to pull off.
Yoshi likes to trade hits, because Yoshi is probably definitely going to live longer than you. Yoshi is happy when the battle is going back and forth with little hits, because Yoshi has decent speed and decent range combined with decent damage that will ultimately let him keep up and win. His great spotdodge also helps this. What Yoshi doesn't like are strong attacks, which force him to shield and abandon his trading games.
I talked to Ampharos about this after, and he made a very good analogy. Yoshi fair pound is a like a reflector or PSI Magnet. You almost never get to use them, because the opponent don't let you, they don't use projectiles much at all agiasnt characters that can reflect or absorb them. However, that's the advantage in and of itself! Similarly, Yoshi having this obscure but devastating ace up his sleeve discourages enemies from ever making any attack that could end up highly punishable--which is precisely the attacks Yoshi doesn't like to begin with.
JGALT would also occassionally get me with it on the edge when he was recovering, during the fast rising of his DJ. I became slightly uneasy about guarding Yoshi; it was far from a big change, but it was one more thing I had to worry about.
