To the OP:
What you fail to see is that the Sorc/Sage hybrid build requires immobility. I'm not sure how you think it's mobile at all. The ENTIRE hybrid build is set up around using telekinetic throw/force lightning constantly in order to get the proc that allows for an instant cast chain lightning/telekinetic wave.
In between the uses of FL/TT, use death field/force in balance. You can't move and cast something that is channeled last time I checked. Interrupts are your friend, use them on the force lightning and telekinetic throw.
As far as the amount of CC's, yeah there's a lot, but they are ALL fragile. In other words, if you do ANY amount of damage whatsoever to the target while he/she is CC'd, it will break and free them, except for the 2 second stun after force lift/whirlwind which isn't really that big of a deal considering the amount of CC's that people aimlessly place on someone.
