That's what I'm thinking, when I went to mess with Yoshi in Melee (Mostly to practice aiming eggs) Falco hardly left the ground but when I used it on Samus in M the Egg went up super high, before she even got out of it. Egg lay might just be like that for everyone, I didn't play too much (Though I'm excited to)
Also, Yoshi's grab game is so good in this, it might have more range than Brawl's too, so with Pivot grabs and JC grabs Yosh can apply some pretty real pressure. No more running grab, yay!
