Not totally sure what thread this goes in so I'll just put it right here I guess.
I was talking with Lord of the Fly yesterday and he brought up a good point about Liu Kang's d3. Against characters with no 6 frame startup moves, they can't reliably interrupt a d3 after a blocked string that leaves Liu Kang at neutral (which is all of Liu Kang's strings). I mean they can still do their own d3 but that's not reliable as the game handles trades in the dumbest way possible: at random.
I was curious who this worked against so I went through the frame data threads in all the subforums. The characters with no 6 frame moves are Baraka, Kabal, Nightwolf, Noob Saibot, Quan Chi, Sub Zero, and of course our old pal Liu Kang. Mostly uncommon low tier characters unfortunately, but it's interesting to know that this works on Kabal. Obviously he can just negate the whole issue by EX nomad dashing between your strings so you still gotta watch out for that, but he's not gonna low poke out of your pressure if you d3 and that's good to know.
