I'm fine with Immobilize stopping the following

Haunting (You basically go "OOGA BOOGA" and then run to where you want to be; according to Dev)
Heaven Kick (Can't do shit if you can't move your legs)
Movement
Rabbit Leap (Same Logic as Heaven Kick)
Leaping Lizard / Winged Serpent / Burn Up / Gain Air (Anything that gives AIRBORNE will nullify Immobilize, but will in kind not give you AIRBORNE)
Parting Shot
Snake Dancer

That's about it.
