Can someone check my priest out?

[Deathcries]

I think my healing priest is having some issues, and I believe he could up his output a little more. However, I don't know if it's due to other healers blocking his heals, but I was wondering if I could get some help to help boost his heals out. I appreciate all the help I can get.

He should not be casting Prayer of Mending ever. His uptime on AA is pretty bad, it's a flat 25% buff to healing and should be used almost on CD(look for a 30-40% uptime depending on the fight. He didn't use barrier for any of the flame slashes on Gruul. That seems like a mistake. More preshielding needs to be happening, you know exactly where damage is coming on fights like gruul and oregorger so there is no reason not to be doing that. He should be using CoW for the tanks taking acid torrent on Oregorger, he's not. He's not using PW:Solace as often as he should be(missed 35 casts on oregorger).

Overall he's not terrible, but as you can see there is quite a bit to work on.

Hey thanks for posting I was looking at your logs and comparing them to myself I am also having output issues. I can keep up with the other healers but I feel I can do some thing else to improve here!
