I really would be sad if they OP shammys to much. Doubt that will happen.

It should be a challenge. Right now we are fighting as underdogs.
It can be done few of our multiboxers are around 1900ish. Rest is either given due or far down the ladder.

Anyways all you can do it hope for some of this boost reaches the live servers.
PTR = Nothing is sure , As u saw on the combining of Mana&Healing totems that is something that they removed.

What is sure Elemental shamans need a boost. The last 100 games i played in arena i met maby 1 team who had a ele shammy.And there is tons of other classes who is not doing arena anymore as u all know.
