Err, it was noted before but yeah, why list a character that beat a character that isn't listed?
If Ramin saw a legitimate reason to pick ZSS, then why not list the legitimate reason? It's silly to just count wins.
Same thing with Istudying, he had faith in picking Peach against me (knowing I don't like the MU), took a close match, lost a second match, and won the last match (close as well) on SV. It wasn't necessarily a random choice, even though the character was only used once, I wager it was used for a reason.
All logic aside though, character rankings are sorta flawed. If I lose my first bracket set, win 5 sets with my Olimar against randoms and subsequently go Wario against my first strong opponent and lose the set (being kicked out of the tournament), is Olimar suddenly the character I play?
Yeah it's all arbitrary, subjective and no this discussion won't have any satisfying conclusions.
