No, because nobody uses Gen in a major tournament. No participant, no rank placement.
Actually, yes, I think so. Even in a major he’ll be left as an enigmatic character. It will also depend on who you face, but there will be always some chun/guile players who will eliminate Honda players, which will work in Gen’s favour (personally, I’d rather face anyone else than Honda). This is regarding that the lack of match-up against him is a tool given to him.
If you do not consider the lack of info on him as a tool, then I’m afraid I don’t think so.
I might change my opinion when AE comes out, or if someone entering a major tournament places in top 8 with Gen.
