The PvE "Sidekick" Shadow Priest build

[Treesh]

Gruul:
We were a little worried about our healing, so I replaced my blue dps items with epic healing items. Then I did dot + flay (mana conservative DPS) for 8 growths, then dropped SF and healed for the remainder of the fight. It worked very nicely, just as I had intended. I was put in the hunter group with their pet shammy Mav so I served as their mana battery.

GG was thrilled at how Gruul went. With you providing VT until 8 growths, the hunters barely had drops in their mana pools. When you switched off of shadowing and started healing, they had enough mana to last the rest of the fight easily without having to drink a mana pot at all and still keep up their DPS.

Honestly, I think your build has shown itself to be a success and will become stronger once you get used to the shadow part of it. Congrats. :)
