why do people assume little mac will rock FD? hes a ground fighter and sure FD has a ground, but so does every other stage, ya know what else FD has TONS of air if you get little mac up in the air he has to fall all the way down to start fighting again. he has no where to land at all. little mac is going to suck on FD. he will rock on tomodachi though (currently unsure if it will be tourney viable but it looks like it) if some one throws him into the air he has several other platforms to land on, fighters with weak air game are the reason platforms are important
I played Little Mac on the Spirit Tracks train.
I got absolutely murdered because it was hard to get close to other characters on the floor, to move around anywhere you had to jump, which made you super vulnerable and useless.
That's not going to be a problem in Final Destination, something that makes Little Mac's ground play even stronger is how freakishly fast he runs on the ground. In Final Destination, you can approach your opponent pretty much instantly, no matter where they are (nobody can stay in the air forever, so even characters focused on aerial combat will have to come down eventually) Anywhere else? You have to start chasing them into the air to reach the higher platforms, and that's when you have to depend on your horrible aerial attacks.
So yeah, stages like Tomodachi Life may had more places to stand on, meaning more ground. But to reach those places you, you have to jump. In Final Destination, you can reach every single spot just by dashing.
