fox and falco are definitely at the top of the tier list, because in the end, they do have the best neutral games out of everyone. However, literally every character in this game can 0-death combo them with a grab, and has plenty of tools for gimping. Falco is not any more unfair than fox is, because literally all you have to do is wait for him to make a single mistake near the edge, force him off and hit him once. The reason that space players dominate is because the spacies are the same as they are in melee. Most melee characters can execute better, especially since the fox tech skill is slightly simplified in project m. I main fox, but hate the fox ditto, and usually play with pit or sheik against fox. It seems to me like a lot of the community cannot execute well enough and are simply playing with fox for no other reason that people saying that he is top tier, and these players are easily wiped out. With the spacies punishment being so hard, it should make sense that they dont have much room for error. Fox and falco are extremely good characters, but a good player would be able to capitalize off the other players weaknesses.
