That video was clearly made in the first month after the release. Sheeva's damage is actually a lot higher now, so add at least 5%-10% to those combos
Yeah I forgot to add that she's had a damage buff since then. Crazy cause she was a heavy hitter back then! I'm kinda glad NRS thought "fvck it, she's supposed to be a Shokan, let's make hit as hard as Goro and Kintaro".
But most of those combos are legit. Her low grab, B2, 1+2, walk and grab does like, 48% and can be done anywhere (beastly for a non meter combo). HOWEVER, the regular walk and grab sometimes whiffs, but i've found the ex version usually connects, for a juicy 50% + combo.
I don't know if it's lag, or just bad timing, but in the training room I find you can pressure people with 2, 1, 2, F1 walk and grab. Even if they block, the grab is safe, then you can low poke and start again. Online I find this hard to do for some reason.
EDIT: Does her fireball/exfireball do slightly more damage now, like maybe, 1% more damage? Man, catching ducking people with her fireball is awesome now!
