Hi, both of your shadow priests are under performing.
On a dummy over 5min 50 seconds with 400ms (latency) (shadowfiend just came off cooldown after i finished) I was able to do 21k in my gear (see below)
Now if we multiply this by 18% (raid buffs 5% crit/5% debuff/5% stats/3% hero-10% uptime)
This ends up being 25k, Bring Flask/Food, Crit->Sfiend shorter CD and Hero for more orbs and shorter Sfiend CD thru fast MF and thats a little more i could do in your raid lineup.
Both your shadowpriests are both under 25k on Hagara. (which has a small windows of extra dmg taken)

Also your hunter is stupid for using a wolf when u have a fury warrior in the raid, he should have CoE pet ready to use.
