You can grab a dispel and just keep on going with Frost Shock/FP but EG will slow you again, and root any of your friends. You also have the option to drop it, rooting the melee character chasing you, then throw the totem at another enemy, rooting them, or to the other side of a pillar you are running towards. It has its benefits.
If you feel those benefits are outweighed by the advantage Frozen Power has of not being destroyed, being a ranged ability (without the need of another talent - though I tend to think for Enhance and Ele at least Totemic Projection seems to offer the most in Arena thanks to Capacitor Totem - my own opinion) and having a shorter cooldown then thats fine. If you feel you're team has plenty of CC but you say have a Warrior in your team (a class renowned for its constant need to be babysat by your healer with dispels) then Windwalk Totem might be your talent of choice. That is absolutely fine. Its not fine to say however that Frozen Power is way better than Earthgrab just because you think so. I will probably take Frozen Power in Mists because I think it procs Shatter which my Frost Mage will love, but that is a unique situation where Frozen Power has added benefits, and that is perfectly fine.
