I think Shang is our absolute worst match up for a lot of reasons that I'm sure we're all familiar with. Kabal gives me trouble since he's safe, his reach is good and his JI1 is so hard to do anything about. Characters that have moves that just blow up the poking game (Jax, D'Vorah and Lotus Fist Lao come to mind) reallty make landing D3s more work. Really good Kitanas make it tough to take your turn or reach them when it is your turn.
