Can't believe you played it and only played with Cody, and an old character lol.
I would have went in that shit. Ibuki, Dudley, Juri ETC.
Cody is mad fun, crazy solid with a lot of options at all times. Dudley felt really weird to me, going to have to have some actual sit down time with him to figure out how to really make him work so I stayed off him after about 3 games with him. Same thing with Deejay, he felt kinda weird. Everyone else I'm not really interested in using. I'd rather focus on one or two characters and learn a lot than keep switching.
Also, it wasn't winner stays on, it was both people go to the back of the line after a few hours of winner stays on. Really loved Cody so I stuck with him. Such a beast.
