I drive from my best mage... then get a group of about 7 - 10 mobs, AoE Arcane Explosion, Blast Wave, and Holy Nova for the win.

I often put a bubble on my pulling mage or highest dmg mage, dropping a renew on him before the pull or maybe multiple toons as Im running through mobs into the pull, then i spam the AoE.

My set up is click through to heal, but I'm rarely using it based on above.

I doubt what I do is worthy of a video (plus I've never made one), but it gets the job done. My group is steady, only rarely do I have a toon die, and I put zones on farm status pretty quickly. It is fun !
