I still think a lot of people don't know how to fight Kano, which is a advantage in his game.
Most people only seem to play or play against certain characters: Cage, Scorpion, SZ, Raiden, Kitana and Mileena. As a result, most people have a fundamental plan when fighting these guys. You dont see a lot of Kano players. Or Skarlet players. Or Freddy's, and so on, and that goes in their favour.
I don't know if Kano is bottom, he's quite low and has a really hard time against Jade and Noob Saibot of all characters, but he has an easier time against top tier characters than a lot of the cast do. I don't care, I love Kano!
