Except barely anyone uses a Mishima. I've fought way more Bryans, Laws, Kings, AKings, Asukas, Lilis and Larses. Have yet to fight Devil Jin, Angel and Heihachi.
Because everyone online is going to EVO...Herp-Derp
Evo 2011 Tekken 6 Top 8:
1. Kor: will probably go Bob/Lars (current team if I'm not mistaken) or Bob/Slim Bob (maybe Solo Bob if Solo is allowed). 2. NYC Fab: plays Bob/Miguel nowadays. 3. Rip: plays both Laws and Paul nowadays. 4. JustFrameJames: plays solo Marshall Law or Marshall/Yoshimitsu 5. Crow: I have no idea who he plays now, but it's probably not a mishima. 5. Mr. Naps: plays Bryan/Dragunov right now. 7. Tokido: last time I checked he was playing Lars/Bob 7. Ryan Hart: last time I checked, played Kazuya/Heihachi. Only Mishima player on the list.
Then we have MYK, who plays Steve/Lars. Aris, who plays Dragunov, Armor King and Feng. Kane, who plays Lili and Alisa. Slips, who plays both Capos. The list goes on. There are not that many Mishima players competing and winning tournaments in the US.
