Earth Wind and Fire ten man achievement with a surprise ending. It's from a Shaman's point of view. For those wondering what's going on we have 3 tanks and 3 healers.

1) Pull Koralon to Archavon
2) Get Koralon / Archavon low
3) DPS + a healer / tank proceed to kill Emalon
4) The remaining 2 tanks / 2 healers on Koralon / Archavon should be able to kill both bosses before their enrage and give the Emalon team time to finish.
