I've been running AV almost every day from 63 to 67 with my 5 shaman. Playing D at the horde base after killing balinda has allowed me to rack up a ton of hks. The alliance filter into the base a few at a time until all the horde side flags are capped. Earthbind totems make a great setup for LB then CL and shock the rest down. I have several AV followers who will find me and help/follow me around. Having a staggered earthbind helps to slow incomming enemies so you have plenty of time to cast. I'm pretty sure if I hadn't been playing D the horde would have lost.
