For now, it's Yoshimitsu and aPat on the side. I suffer from HEAVY character crisis though, so I've been playing Cervantes, Viola, Mitsu and Pyrrha lately as well :s
But Yoshimitsu is prob gonna be my homie forever, it's something about the YOOOOOOO and NAMUUU whenever he attacks that just entertains me way more than any other character. You play Natsu, right?
