In case anyone was curious, if you do manage to mind game Quan Chi into raw trance while he's in the corner (don't tell me this doesn't happen, Quan does it all the time to punish unsafe clones, and Madzin was baiting Ketchup into it after b12 so shhhhhh shh shh shhhhhhh), optimal punish as far as I know is...
(reversal) ex ice statue, ji1, b12 xx ice burst (shatter), d1, b12 xx ex ice blast, njp, jip, b12 xx slide (50%, 2 bars)
-or-
(reversal) ex ice statue, b2, 24 xx ice burst (shatter), b12 xx slide (45%, 1 bar)
Ex statue cool down was too long for me to get the meterless freeze. I tried ex statue, b2, 24 xx shatter into (...1, 1, 11 xx clone) and into (11 xx ice ball), but unfortunately neither one worked. If anyone can find a decent work around, that'd be awesome.
Note that after reversal statue, run b12 starter yields the same damage ji1, b12 does, if you prefer to stay on the ground/ less hits (be aware however, that for some reason starting with b12 instead of ji1 gives Quan slightly MORE meter, despite the combo being one less hit. Comes out to almost a full bar). Ji1 is not an option in the b2 combo because ji1 doesn't combo into our OH at any height.
Pretty good use of meter in the MU if you want to close out, or spend a bar/ 2 bars for heavy damage. Combo is ended in b12 xx slide because it's Quan Chi and he can't do much about it, but feel free to end in f12 for the safe clone and slightly less damage.
