Let me correct myself. He wasn't absolutely fucked in every matchup and furinkazan was almost always a table-turner. He'd score good damage if it was possible to combo after 623b without the followups dropping after 5a/5b, or you were fighting a 6c-able character. His mix-up was also fairly strong.
That build would honestly work in CS, mostly because of the changes combo system.
