you must really suck because mac is stuffty in the air and has subpar recovery
I got SSB4 around november, the main problem for me is not his abilities but the fact that he is used almost always in a match.
I don't believe I suck, I certainly am not the best player, but I do have my strengths when it comes to Ness.
EDIT: I just realized I've never won a multiplayer match, so I guess I do suck.
