Second : I use the glyph which give you back 100% of the cost of your totems, you can save A LOT of mana if you call back your totems when it left 0s ( with exp, you can call back after his last tick ). Don't wait too much time before using your mana tide.
Always, everyone heal like he want to heal, you can go with 6k spirit or 12k spirit. But for your concern ( ele stuff ), i think you should try to manage your mana instead stacking spirit. I am at 6k spirit and 6/6HC 10 man and i am happy with it. ( i run with int food and in flask )
