From watching people's streams, it seem like run canceling got a universal nerf.
So we've got this situation:
Run canceling got a universal nerf.
Liu Kang got a specific nerf to his cancels, which seems to not take into account the universal one.
Quan Chi got a 6 frame D1 to deal with block infinites, that no longer exist, and double don't exist for Liu Kang.
It's like the people working on this game don't talk to each other before they compile the code. Also, Honeybee found that D'Vorah's cancels into all options using 1 from WGC are ALL bugged (D1, F1, etc), which makes me wonder if this isn't affecting Liu's cancels as well.
