Tell that to all the bosses I've topped meters on with most healing done by Atonement. Bosses you've never killed.
Hate to pull e-peen rank, but just because you've never done it doesn't mean it isn't good.
I really doubt you hated pulling e-peen rank, since it was essentially the first thing you did. Can you actually provide an argument that isn't "I've killed this boss, you haven't, therefore I clearly know more about playing a Disc priest"?
The impression I get from your logs is that your other healers aren't that good. You're seven healing everything I've found, and it's pretty sad that your effective Atonement healing is so prominent given that fact. Then you look at Damage Done, and see that you're doing nearly as much damage as some of your worst DPS.
If you're healing heavy damage phases with Atonement on 25M and topping the meters, I'm absolutely shocked that your guild is ahead of mine, because it means I'm seeing poor play on three fronts.
PoM is also really weak right now, despite being a smart heal.
Could you name a heal with higher HPM or HPS?
Self buffed, PoM hits me for 23345. Let's say it's fully effective for all 6 heals unglyphed. That's 140070, or an HPM of 13.34.
My PoH (heal + DA) hits for 45823. Let's say it's also fully effective; that's 229115, or an HPM of 16.97. I have to go down to it hitting only 3 people for full effect for it to be less HPM than PoM.
My Spirit Shelled PoH has an HPM of 19.17. Again, I have to go down to 3 for it to be less HPM than PoM.
HPS is going to be a lot more unstable for Prayer of Mending, too, because it absolutely depends on how and how fast the damage is being distributed, but PoH is going to absolutely trounce
PoM for HPS unless you're Holy and it's a Divine Insight PoM. I mean, go ahead and assume damage is being taken at 1 second intervals. That means PoM is healing once every second. That's 23345 HPS. It takes me 2.3 seconds to cast PoH. Assuming just the heal is effective, that's 59782.6 HPS; if we add in DA and calculate it at the 3rd second, that's 76371.7 HPS.
