Beat me to it!

Basically Shabu tanked sarth and tenebron, and I controlled Korovyov and the 8 shamans. We have 2 resto shamans and 6 elemental shaman dps. All 8 shamans followed me, and I controlled the dps on adds and tenebron while dodging flame walls and void zones. We zerged down tenebron to kill him as fast as possible. Because all the alts were on follow, the adds were very easy to pick up since they were centralized. The hardest part was trying to keep 6 things in mind at the same time (whelps, fire elementals, tenebron, tail swipe, void zones, and flame walls), but it definitely made victory all the sweeter.
