The important thing is moving the monster out of the way and ensuring its location at a given time. This pretty much ensures that other PCs will be able to pull off a planned combo against the creature when it comes down.Would you mind explaining how? Daze+Immob are powerful, but not if they're explicitly not in effect during the monster's turn.
It's also good for a wizard who waits to interrupt a special attack he or she knows is coming. For example, the shadar-kai chain fighter has an ability to slide around the battlefield and attack different targets. The wizard could wait until one of the chain fighters began to slide and then isolate that chain fighter with pinioning vortex.
