2nd one is silly since vanish will still get them 3 sec away, regardless of damage.

3rd one doesn't work on players since they are immune to taunts. I still keep Dark Command bound with Outbreak and Death grip.

This guide has many flaws, the most incredible being:
"When a Warrior is Bladestorming one of your team-mates, Death Grip it off them. When in Dalaran, Blade's Edge, and Ring of Valor, you're able to Death Grip the Warrior off a pillar or ledge during the Bladestorm, but you have to watch for a Grounding Totem and Spell Reflect."

I wasn't aware that a blade storming warrior would use a shield to spell reflect, or that you could deathgrip him while he was unstoppable...
