The macro I have right now puts down a magma and cast nova. It's timed so I should always get a magma down before it expires. I was thinking of making a macro in isboxer like my mind freeze for wind shear round robin. It will lower dps but would be casting interrupts rotating through 5 shamans. That would be nice in pvp. I have the tremor round robin setup and tested that out in AB yesterday. My lvl 81 guys with 40k health were ripping through lvl 84's with 85k health like a hot knife through butter. The stoneclaw totem gives me a shield so I can drop that with all of them before a fight to give myself the shield. At this point I figure my healing would use my mw x 5 or x whatever number is up. If I have click healing I could have them all chain heal. Or I can macro in a chain heal every 10 seconds or something. These guys have lots of options. I love how fast they kill stuff verses standing there waiting for cast to launch. Melee is a blast!
