Things to note:
Sort of like Gothik + "Reverse" Vaelstraz, green dragon Valithra Dreamwalker sits in the middle being "Corrupted" starting at 50% HP. Healers need to heal the boss to 100% to end the fight.

4 (I think) portals spawn every so often and healers need to go into them, they then enter a dreamstate and there are clouds floating around that have 100 health and need to be killed to give the healers a healing buff. In order to gain the buff you must stand near the cloud as you kill it. The way our guild was doing this was by stacking all the healers together and 1 person killed the orbs.

Adds continuously spawn faster and faster from 4 gates in 4 corners of the room, there are several different types of adds.
These are (not sure on exact names):
1) Supresser - these do not have an aggro table and apply a debuff to Velithra that does -10% healing done (High Priority)
2) Blazing Skeleton - these are caster adds that do have an aggro table however you ignore it because after 3-5 seconds they begin channeling a large (zone wide?) area of effect called Lay Waste which deals a significant amount of damage per tick (#1 Priority)
3) Abominations (not full name) - regular tank and spank after about 5 seconds of killing some worms (can't remember the name) spawn out of them and need to be tanked + AoE'd down (Low Priority)
4) Risen Archmage - regular caster mob does need to be tanked does a Frostbolt Volley (large range) that slows everyone (Medium Priority)
5) Zombie (not full name) - Tank'n'spank explodes when killed putting a DoT on nearby people (including boss). (Low Priority)
