People said that a month ago, two months ago, three months ago, and the game has already progressed quite a bit and continues to progress.
Its a new game, there will be new people who are really good, thats what happens when new games come out. By your logic, when Ken won TG4, it proved that Melee was shallow, because any random could win. When Mango placed high at EVO, it proved that Melee was shallow 6 years after it was released, because any random could place high. The truth is though, thats awful logic, I guarantee if you ask DSF, he will tell you Futile is really good. Do you even know who Futile plays as? WARIO.
People are good when they are good, its that simple, and when a new game is released, the skill levels of everyone are closer because everyone has to learn the new medium, so its no surprise that new faces appear, because these new players have the opportunity to grow with a fresh game, instead of coming in 5 years after a game is released and having to learn everything at once, they instead learn it in the same steps and pace that everyone else is learning it.
However, the best way to refute your argument is quite simple, go out to a tournament and prove how easy it is by winning it.
