Which, again, is wrong, since Liu Kang blatantly states that there was once one timeline, but now there are many, with each alternate timeline representing a different possible outcome against Kronika, Liu Kang even saying that those possibilities are endless.
At the very least, if a concrete 2-A rating isn't give, it should at the bare minimum be "At least 2-B, likely 2-A". But given that "endless" practically means the exact same thing as "limitless", "infinite" and "boundless" in terms of basic English comprehension (With there being zero chance for Liu Kang to bullshit here), 2-A would be the most accurate rating.
