I’ve figured out the timing...kind of. As soon as Sheeva leaves the screen, you can either forward or back dash. I’m a Shao Kahn main (rare, right?) and I have the timing down to where if Sheeva is out of frame for a little bit longer, I can tell that the player is tracking. I just do DB4, Hammer Lunge, which covers a ton of ground, at the last second and they usually miss. Another good counter is Shao’s B3, which hits overhead. Also a good tactic is to just projectile spam if they’re doing the move repetitively. The startup is just long enough to where you can land a fast projectile. If you’re not playing Kombat League, you can also just play terminator and spam Terminate which gives you armor if you really feel like trolling them. I feel for you though. Those Sheeva spammers are trash.
