Pre-80, Elemental Shaman seem quite vulnerable in PvP. No stun, no silence, no interrupt. We have Frost Shock and Earthbind Totem for snares, but honestly, not worth a lot. I find that my survivability drops like a rock if people spot me in PvP.
At the same time, I've been at the receiving end of an Elemental Shaman's Chain Lightning + Lava Burst combo, and the damage output seems... fine, shall we say?
How to balance it?
