Kazuya's reveal was probably the biggest expectation-breaker since Joker. Master Chief rumors aside, we generally agreed that DLC Mii Costumes at least deconfirmed the series, right? Why release them separately when you can have an entire theme? Spirits were generally in the same boat, and while heavily debated, most agreed that an AT promotion was just statistically unlikely due to how few viable options there were. There was a general agreement than the presence would be all with a pack or the series wouldn't have a fighter.
Then Kazuya tossed that off a cliff, alongside Ganondorf. And Captain Falcon. And Pit, and Min Min, and Marth. And he tried with Kirby, be we all know how that's gonna end.
He's fun to play, if not hilariously complex - Often times I just throw out whatever input I remember first. Stage-wise, though, I feel like the Mishima Dojo is kinda bland. The mechanics are fun, but the backgrounds feels too dark and monotonous, and there isn't any cameos to spice it up beyond Heihachi. Still, I generally approve of Kazuya's pack.
