Sethlon, you're just that much better than most of the people that show up to your tournaments. Hell, even I won a (small) tourney with Link back in like early '09. Point is, there will always be straight up booty matchups for the character, and it just takes a player at a high enough skill level to show it.
Like at that crew battle, even though I'm not fluent at Melee, when I had to go against you (you were the last person left, too) with my Sheik, you went Fox instead of your primary main Roy, and I'm sure you did it to give your crew the best possible chance to win, because Mew was next as the last person after me on my crew. I'm sure you would have still destroyed me as Roy, but you didn't want to take that risk then at a horrible matchup. See what I'm saying? At the end of the day, bad characters will still be bad characters no matter who is behind that character (not to bash at the players who choose the character; I understand what it means to pick a bad character, whether it be out of fanboyism, a more difficult challenge, liking that certain playstyle, etc.).
