Hi there,
I am mainly playing holy, occasionaly disc but i want to try out shadow aswell.
Some logs there:

AoE (Beastlord Normal):
warcraftlogs.com/reports/T1PdHaxcqvKmN3t9#fight=22
Imperator Mar'gok HC:
warcraftlogs.com/reports/3D9yHgJ7akLx8AjF#fight=5
Gruul HC:
warcraftlogs.com/reports/xHBy8JqG76hr2bRp#

I think i am doing something srsly bad, comparing to other Shadow Priests logs.

I've bought: Sandman's Pouch (640) to try it out because i don't have 2nd DPS trinket.

There is armory:
the-maelstrom Elliel
(yeah I know there could be better enchants, but it's my 3rd spec).
Dotweave:
4orb -> MS - SW:P - VT - MB - DP -Ins -Ins - MB - DP - Ins - Ins.
For multitarget I am trying to keep SW;P and cast MB on CD and add to this some VT. If group is stacked I use Mind Sear.
Basicly my gear is just my healing gear + the rest what my team don't need.
