I have a 68 elemental shaman and am really enjoying battleground pvp. What is the best spell rotation for burst damage assuming all cooldowns are available I can instant cast a lightning spell, thunderstorm and shock spell.
Well, shammies only really get a heavy burst when they hit 75. Until then, I would suggest Elemental Mastery + LB + Frost/Earth Shock (depending on which one does more damage at your level) as well as thunderstorm at level 70. Essentially use all your instant casts, as until 75, there is no spell that will always crit for high amounts of damage.
