Honestly... all that really doesn't matter
its the fact that every single one of Flashes wakeups aren't stuffed by our WC/C setups, but rather you go THROUGH Grundy. He cannot Oki this character, and that is a huge huge problem, considering a good portion of the game revolves around "who can get up and who can't" for Grundy.
Grundy doesn't care about your LC stuff... because we are going to be WCC our way in at the distance where you would typically "yolo" it out there anyhow.
SP actually isn't very good, because it typically just goes over Grundy and whiffs when you don't expect it to, or you just get d2'd out of it on a read (guess). At least I LOOKED for the SP because I can't do anything about the post LK anyway.
My opinion anyhow from when I played SEV. Flash still wins because he can keep himself safe from the armor and doesn't have to fear the Oki off any type of KD.
