Like I said, as a multibox we have some utility for it.

But as far as the skill goes, it's still not enough for any solo elemental shaman. I also have a solo shaman and really, against ALL melee classes, TS saves you about 2-3 seconds before you get owned. So as far as the skill goes, it is by far, not imbalanced.

The fact we can round robin it 4/5 times makes it good, but that's it. Elemental shamans are still the single most nerfed class in endgame pvp at the moment.

All melee classes can counter one TS.

Warrior -> Intercept Hamstring = dead
Ret Paladin -> Dispel + JoJ and boots speed enchant = dead
Rogue -> Crippling, stuns, shadowstep, CloS, so many stuff = dead
Druid -> Shapeshift out of slows, feral charge = dead

Enhancement shamans can actually be kited, the one melee class Thunderstorm is effective against is another shaman.

So seriously, it's a joke for a 51pt talent. We need CC similar to poly/cyclone/hoj or anti cc abilities, going ghost wolf removes snares/slows etc for example.

Anyhow, for a multiboxer it has potential, but as far as I know, blizzard doesn't balance classes based on multiboxers.
