Thanks for the tip; I forgot about thunderstom mana effect (and may glyph it to avoid having to run after my targets; though indeed I like the knockback effect in pvp and emergencies and can't quite afford dual spec) - What I just did (but haven't tried in instance yet) is I made 1 of my shammy resto - I hope Mana Tide totem will eliminate my mana issues - but we'll see about loss of dps
