So far the only match I absolutely need Rolling Thunder for is against Honda. Against every other character I feel like I would rather have the ability to get that little bit of extra damage in with Cork when I need it, than have a mediocre fireball punisher that doesn’t actually work against a few fireball characters.
Even against shotos. I already have duck, focus, and well spaced jump ins to get around fireballs just fine. So once I am in, I want to maximize the damage. I’ve managed to win a lot of rounds off of an EX Cross counter -> cork for the last bit of damage. Or just having it there for that final corner finisher after a crouching RH. As much as I like styling with a Dempsey roll, it really does feel like a sub par ultra except against Honda. Being able to punish headbutts with RT feels absolutely vital for the match.
