Just came to say. I laughed at people saying that rolls were problematic. I thought there were enough options to force the opponent out to do a bad roll and then punis, or just onslaught them with aerials with low ending lag. And actually i did so against a lot of people.
I was very wrong.
Actually i think yoshi has no way, at all, to combat rollers. His only coverage options against rollers are grabs (and they are risky), dash attack, jab and nair. None of them can kill even in 200+ (nair sweetpotted maybe, but it ends stalled because is the best coverage move against rollers). I have had 2 stock matches go to a loss becuase of opponents going into desperate mode and start rolling after every attempt of attack or worse, just waiting for me to attack and rolling, then punish; and being totally unable to deal the finish blow on them (or have my usmash perfect shielded/missed by some random gimmic of the character (greninja's crouch after hitting the ground after upb)) or stuff like that... while i keep getting damage with more percentage and moreeee percentage.
I'm sure most characters wont suffer from this, because they either have strong rolls, grabs, or some coverage moves who can kill, (or good proyectiles who can kill or keep away with) but at least yoshi doesn't seem to have any way, at all, to deal with them. The only way is hard reading them the moment they start waiting for your actions to roll, and it comes down to 1/3 of guessing right, and sometimes even less considering missinputs (because of the little time window to hit in some characters). Also, yoshi's slow roll doesn't let him do the hit and run tactic most rollers do and after a miss he WILL get punished HARD, while most people can just dance his way.
Really depressing situation. I have had matches went into a hellish uphill simply because the opponent started rolling every attempt of agression i had. And if you don't remember, yoshi's baaaaad standing grab doesn't let him play the defensive game: the only aerial it can use OOS is nair and it only hits in reaaaaaallllyyyyy close opponents.
Against the rest of fighting styles, yoshi is very good, and posibly S tier or higher. Yoshi's moveset let him be able to deal with many situations and counter a lot of aproachs while maintain pressure. Is somewhat weak to people shielding or playing defensive but his B let him have some options to punish passive people. But oh man, the rolls. The ****ing rolls. -.-
You can try. Do any attack as yoshi, roll with greninja behind him, and try as yoshi to get something before greninja grabs/jabs/fsmashes/usmashes you. You can't or at the very least greninja can go away and reset neutral veeeery easily...
At least and not last, the standing recovery from the edge seems broken with some characters. The invencibility frames last until the character can act again (and for some characters even a little more, being able to act with invencibility frames on them). Some long lasting moves can counter this but not always. And, wonder, Yoshi doesn't have any way to punish a guy who gets up normally because the only thing he has to do is: wait for yoshi trying to hit you below the edge (with dsmash/dtilt/fair in the edge)... you then get up normally and roll, or get with R rolling into the stage; or wait for yoshi to be in front of you and try something to get you, in which case the "best" move is posibly dash grab; the rest of moves are easily dodgable on offensive or "useless" in defensive (except nair).
If someone has something i have oversight, please, tell. But right now i don't see any way to deal with them.
For the rest of characters i don't see at the time anyone who has these 4 factors: bad/slow rolls, slow grabs, coverage attacks who can kill, or spamable proyectiles (mind you, yoshi's up b is a great proyectile but easily punishable in certain distances, and i mean, really, easy. As easy as running below the egg and usmashing).
I look forward for your insight on this topic. Thanks
