I had the same issue as Druids; they're effing nature immune so no roots, no IS, no wrath; either MOonfire and waste mana or get hit and take 8seconds to cast a single Starfire. My solution? /guild WTB help killing nature-immune Elementals or /1 LFG/LFM Questhere ;) Thankfully only a couple of quests require you to kill 'em; in your case, Flame Shock(if Frostshock doesn't work) and Searing Totems are going to be your friends. Otherwise, make friends ;)
