Here is an outline of my interface (which happens to be right as I hit 70 ;p)



As you can see to the left I have all the group totems, grounding tremor, wrath, healing/mana stream. These are bound to function buttons. On the right I have specific totems which only the main will cast occasionally. I ran with a castsequence macro for totems which was just one button. But I decided after I reformatted that I would need to have grounding and tremor on their own buttons anyway so why not have the rest dedicated as well. Hope this is helpful
