Yeah, but even Luigi isn't top tier.One one hand. In Smash 4 and in Ultaimte characters that have both very poor mobilty and very stubby range have always suffered abd never could escape lower-tier I.e Kirby and Doc..
UNLESS the character, despite those flaws has some nutty combos and jank that could allow them to basically steal stocks when they actullay could get in i.e Luigi.
Steve does look like he can fit into the latter category from what we have seen. With soek examples looking at least somewhat practical. But so far I think we have to see one player really be able to fully Grasp Steve and use him to his full potential to see how good he is
