Maybe something like this is what elemental shammies need?

[Dominian]

Anti-polymorph ghost wolf form.

Something like that is what I hope for tbh. Would solve arena viability problems quite a bit. We'll always be a defensive playstyle in PvP, true. But I don't think making a heal instant makes much difference. The ability to kite might on a consistant bases however.

I could agree that maybe ench shamans could need it but there is no need for elemental/resto.

You got 3 ways of avoiding this:

1.Los and poly is quite easy to los
2.Earth Shock
3.Grounding totem

In addition your team mate or mates atleast have 1 way to interrupt it, so i disagree that poly is a problem to a elemental shaman. So i dont see why solo boxing shamans should have any need for this at all im afraid.

Now the main problem is beeing focused by meele, and the only thing you can do is thunderstorm and flamshock/earth shock/frost shock. Not nearly enough to kill a rogue/retadin/warrior/feral druid.

The idea was actually to make ghost wolf break snares in the launch of WOTLK but blizzard went away from this due to it was "To close to the druids core talent shapeshifting" I do assume they feel the same way about ghost wolf breaking poly.

I totaly agree with you that a self heal wont fix anything since our worst enemy is rogue who already apply wound poison.
