Soloed this 5 times so far with my shamans in blue pvp gear with only the merciless shield. (tow specced however)

First pull

2 earth elementals and 3 fire elementals

Spread out and heal the earth elementals and pop bloodlust.

Secondpull i use 3 earth elementals and 2 fire elementals.

After this you have to wait 15 min on the elemental cooldowns.

Then start it over.

On the last i use 5 earth elementals and its realy easy.

HOWEVER there are mana issues atleast for me (7k mana) so i have to pop a Super mana pot in 90% of the fights but its SOOO worth it! 2 spelldamage trinkets so far!
