I haven't experienced any problems with it. I use it on CD as much as I can.
Maybe you should try putting a point into Force Grip. You can choke a target on one side of the room building threat, force leap to another target, hit it with sundering assault, hit tab to taunt and force scream the third target. Backpedal to bunch up the mob and then have the dps use aoe ontop of you while you use Sweeping Slash.
