This is wrong. When the game came out, everyone thought Falcon would be great. He is a popular character. LOTS of people love and pick Falcon, including top pros. They tried using him to win. They failed. They moved on. Yeah, if every pro picked him he would be higher than he is, but he wouldn't even make it into mid tier.If for some reason the top players thought Captain Falcon was the best and only played him (0% possibility) then he would be the one dominating. So basically whomever the top players flock to will be the one to do best in the tournament scene.
You make a good point about Metaknight being the best but the difference not being 1.6, but don't say such silly things like Falcon would be the best if pros picked him to make your point, it makes your good point get completely lost and ignored because of such comments.Tournament placing doesn't determine a character's potential, it only determines how many top players each character has. Meta Knight's lead above everyone else isn't because he's that much better, it's because so many good players use him. Don't misunderstand, I'm not saying Meta Knight isn't the best; I'm only saying that Meta Knight isn't as good as the difference shows. He's not 1.6 times better than the 2nd best character. That number is inflated by the top players focusing on him.
Also, I personally think a great way to see a character's potential is to see how well they do in tournments factored out by how many people actually play the character. Ahem, Peach s in B rank, despite how many people actually use Peach in tournies? Not much
