Is Yoshi a good secondary for Luigi?
That is to say: Does Yoshi improve upon Luigi's bad matchups enough to be worth investing time into learning?
I'm interested in Yoshi because I played Yoshi back when the 3DS version dropped and I remember him being fun, but again, as a Luigi main, I don't want to invest serious time into him unless he actually covers or improves upon his bad matchups.
Now I am only recently getting back into the game, so I'm not 100% sure which of Luigi's matchups are actually bad enough for a secondary, but from what I understand; Sheik, ZSS, Rosaluma, and Villager seem to be among the worst for him, but there could be others.
Anyway, just wondering. Yoshi's aerial mobility seems to be perfect for this duo since a lot of Luigi's problems are due to his terrible air speed. But I could be wrong.
