I'm going to define "high tier" character as one having recent top results at a major tournament. Based on this definition, Pikachu is "high tier" literally just because of ESAM. No one else (that I'm aware of) plays that character anywhere close to such a high level.
Let's assume that Yoshi and Pikachu are roughly equivalent in that they can both be "high tier" if played by a suitably good player. How is ESAM using Pikachu's potential to its fullest and why aren't Yoshi players doing the same?
So, here's ESAM taking a game off of ZeRo with Pikachu at CEO 2015 (one of the few to do so):
https://www.youtube.com/watch?v=v-jljs8psXk&t=7m45s. Because it's ZeRo losing, no one can refute this is an important game to look at. During the game, ESAM used:
Uspec 16
Fspec 1
Nspec 31
Dspec 4
Uair 22
Fair 14
Nair 9
Bair 6
Dair 8
Utilt 5
Ftilt 0
Jab 0
Dtilt 4
DashA 1
Usmash 0
Fsmash 2
Dsmash 1
Grab 12
Shield 18
Roll 6
Dodge 8
Kill 1: (Sheik @ 124%) Roll -> Dash -> Grab -> Dthrow -> Jump -> Dspec (Sheik @ 158%)
Death 1: (Pikachu @ 176%) Shield Drop -> Fair (Pikachu @ 182%)
Kill 2: (Sheik @ 121%) Roll -> Grab -> Uthrow -> Jump -> Dspec (Sheik @ 148%)
As a Yoshi case-study, let's look at KDB's play. He was the highest-placing Yoshi at CEO 2015 (top-32) and was sent to the loser's bracket by none other than ZeRo himself. Here's a very close game between him and Phuzix (top-24 Sheik at CEO 2015) from last month:
https://www.youtube.com/watch?v=29y4n97aOCo&t=2m45s. During the game, KDB used:
Uspec 23
Fspec 0
Nspec 2
Dspec 2
Uair 4
Fair 21
Nair 23
Bair 0
Dair 0
Utilt 0
Ftilt 0
Jab 13
Dtilt 0
DashA 0
Usmash 1
Fsmash 1
Dsmash 0
Grab 1
Shield 17
Roll 1
Dodge 20
Kill 1: (Sheik @ 61%) Jab -> Jab -> Jump -> Fair (Spike) -> Fsmash (Sheik @ 96%)
Death 1: (Yoshi @ 121%) Grab -> Pummel -> Uthrow -> Jump -> Uair (Yoshi @ 137%)
Almost Kill 2: (Sheik @ 91%) Roll -> Jab -> USmash (Shielded, Sheik @ 93%)
Death 2: (Yoshi @ 136%) Grab -> Pummel -> Fthrow -> Jump -> Fair (Yoshi @ 150%)
Watching both games, there are some similarities:
- Both players use defensive options very well (For Glory scrubs like me roll all over the place, ruining our options)
- Both players ONLY use smash attacks when they've read an opportunity for a kill
- Both players essentially never use dash attacks
- Both players rely heavily on projectiles for spacing when transitioning from Disadvantaged -> Neutral (Nspec for Pikachu, Uspec for Yoshi)
- Both players rely heavily on quick aerial moves for setting up strings (Uair and Nair for Pikachu, Nair for Yoshi)
There are, however, some very glaring differences:
- KDB spams air dodges while attempting to transition from Disadvantaged -> Neutral a bit too much
- KDB never grabs while grab is ESAM's 5th highest offensive input
- KDB only uses 3 of the 5 air options Yoshi has (mostly just Fair and Nair) while ESAM uses all 5 of Pikachu's air options (though mostly Uair and Fair)
- KDB uses Jab as an option fairly often, while ESAM uses a combination of Utilt and Dtilt instead
- KDB's kill (and his very close kill attempt) were sub-100% on Sheik, while ESAM's kills both started over 120%
- KDB's deaths were at lower percentages than ESAM's death, but still began over 120%
To me, looking at this, I really feel Yoshi and Pikachu are very similar. Both of these players also seem extremely talented on paper and exhibit the kind of play you should expect to see at a high level. The only glaring differences, to me, are:
- KDB's slightly sloppier and more linear play when compared to ESAM
- Yoshi's complete lack of a grab option
- Yoshi's ability to kill far earlier than Pikachu
- Yoshi's lack of "viable" options (8 of 18 were completely unused by KDB - more on this below) compared to Pikachu (3 of 18 unused by ESAM)
We complain a lot about our lack of a grab, but we may not even need it. Compared to a character like Pikachu, we dish out way more damage in the average string. We also, arguably, have a better way to fish for these strings (better control on our projectile, retreating Fair, quick command-grab) to make up for our grab. On top of that, we have a lot more options to kill early.
I think Yoshi mains, in general, need to work on their ground game. Raptor came to the same conclusion after my post ~2 months ago in the video thread. KDB, as an example, simply doesn't use Dtilt, Ftilt, or Utilt as options, despite them being very good. Utilt -> Utilt -> Uair is a thing and tacks on more damage than Pikachu's equivalent Grab -> Uair -> Uair/Fair. It's just harder to set up because the initial Utilt isn't as guaranteed as a grab.
Ultimately, the conclusion I've come to as an aspiring player is that Yoshi is "high tier" material, but very difficult to play optimally. Many of our less-used options are very punishable compared to Pikachu, which is why they aren't used (Bair, Dair). We also have a completely worthless move (Fspec) that nullifies an available option. This is the linearity that Dabuz is talking about. We need to be able to throw out some of these moves as mix-ups to catch our opponent, but not get #rekt doing it.
Hopefully this analysis pushes some of you in the right direction. I want to see a goddamn Yoshi top-16 a major!
