I'd be interested in some tips as well because while I raid as ele I just can't get a handle on it pvp wise. Besides blasting people to their doom using thunderstorm at the flag point in eye of the storm it's a bit rough. Large scale BGs where I can stand at the back and free cast are fine but in arena I find it hard to get a cast off and just fishing for a lava surge proc. Shaman in general seem to be the preferred kill target out of the gate and I haven't really been able to do any decent damage without being totally shut down. I just pvp as enhance now, brutal burst, self heals are good (and instant with maelstrom weapon procs).
