Is Yoshi on the same list as Rosalina now? The whole "This character seems good but has minimal results perhaps barring 1-2 notable players" list?
No, because Rosalina actually has players all over US/Japan that does well on a national
and regional level. Yoshi does not.
I'd say the characters that fits the whole "In theory, this character can be good but nobody has unlocked the potential for them yet" is more of... Peach Toon Link Megaman and Greninja maybe? (including Yoshi in the list as well) Though I'm tempted to say there's really nothing to unlock with Yoshi right now lol
Just need to change up our playstyles maybe to do well.
Though honestly, there's so many problems with Yoshi that there'd need to be a patch that fixes stuff for him on the level of Shulk early on in the first patch, or most recently Robin/WFT if people wanna see Yoshi in the top placings.
Yoshi is a character filled with
decent tools, but they're all rusted and won't fix a damn thing.
His neutral is not the greatest relying on a frame 16 move to do well in it, he has no good kill set ups, (I swear to god if any of you say "fair" or Utilt to Uair, I'm gonna chew you out, first one isn't even a kill setup and 2nd one can easily be jumped or airdodged away based on your characters weight/fall speed, same story for Jab into Usmash) and he gets absolutely no reward from his grabs nor throws similar to Samus.
Every character in the game has either a kill throw or a kill set up, or maybe even
both (hey sheik, 50/50 chance for a stock from dthrow) He's basically missing 33% of gameplay when you choose him, you might as well take Grab off your controls since the damage knockback and reward from the laggy grabs and pitiful throws is, well, pitiful.
His reliance on hoping his opponent doesn't know how to get out of some of his very few gimmicky set ups or remembering they have a shield button is what makes him "seem" good to people.
tl;dr literally noobtube the character, can mash your face against the controller and do well on for glory while you'll get comments about how broken Yoshi is from roll glory only players.
But if you try and do that stuff in an actual tournament setting you'll find out real quick it's not gonna work once you get past round 1 of winners and face the real players at your local.
