Personally my shammy team was and still is IMO one of the most enjoyable to level up. Post 60 is just a cake walk. Between proper spec, glyphs, and water shield I never drink accept after a boss fight. I don't bother with totems unless fighting elites/bosses. I'd suggest getting the Astral Recall glyph as well since it will reduce that spell to 7.5 min which is insanely useful when questing since it will save you time running back to turn in and pick up more quests.
