Have your Main Tank pull this mob toward the wall behind him, then have the MT group stay tight as LoS issues will come up from time to time. Rest of the raid will be assisting the Off Tank. At around 75% or so a message will pop up warning you that a mob will spawn, which is a heroic ^^^ add which has a pretty nasty AE (hits harder than the main boss). Have your OT group meet the add and be careful that they turn it away from the raid or else it means a wipe. At this time you will notice that a targetable but non-killable baby dragon will be running to groups of eggs. This mob will spawn three more adds (down arrows), but they still can wipe you fairly quickly. Once those are taken care of get back on named until next message about add incoming. Rinse and repeat.
