In my opinion, it is hundreds of times better than the magnet grenade. It stops wizards from releasing their queef clouds and shooting bolts of lightning, it stops any non bosses from teleportation, it also keeps guardians from flying in the crucible. And it will even stop a blade dancing hunter in his tracks and make him turn back and run like a bat out of hades.

I'm going to have to try that out. Thanks for the tip!
