Ok, for starters, I'm sure SOMEBODY's found one, too. I don't claim to be the best MK player here.
But, if anyone wants a MASSIVE combo for Jade, here it is:
Start in her Bojutsu stance and hit 2, 3.
Then, once they're in the air, hit L1 to switch back to Fan Zi and open up the following combo on them, juggling them with every hit (the timing on this takes some getting used to, but it works):
2, 2, 1, L1, 4, L1, 1, UP + 3.
If you do it right, you'll be able to rape them with a ten hit, 54% damage combo.
Also, I've found several combos for Dairou that do between 35 and 40% damage.
:P
