My stat priority might change to Spirit then Intel based on tonights raid and feel of mana.
I want to express my complete satisfaction in the ability of Holy Priests in Heroic MOP content. When i hit 90 2 days after MOP release i went with two other guildies who were tailors to the tailor vendor and between the three of us bought every slot cloth spirit pvp gear, IL 450. I then obtained the required IL for heroics in about 10 minutes after hitting 90.
This is where the fun happened. I got to do Heroic dungeon content in MOP.
First dungeon did not go so well, i tried to heal like i did in Cata, it did not work. I went OOM over and over, plus my HPS (Health Per a Second) was sitting at 12k. I was hitting 25-30k hps in cata heroic content Dragin Soul. I knew something was wrong. I then decided to use the one spell i hated most of all Holy Priest spells "Renew", since reading in the forums everything was pointed that way.
The sad but happy story of Renew then began. it took 1-2 dungeons to get used to using the Holy Word Serenity's Renew mechanic. I then found a renewed love for the plain Heal, which was my most used spell in Vanilla, and the chakra spell Serenity. Those two spells combined with Renew and the mechanic of Chakra Serenity were putting my numbers around 25k hps and i was not OOming. Also i was using my Shadowfiend on the 1 minute CD and it should always be used on CD even during trash.Keep in mind that i may have 1 piece of Heroic gear at this point but mainly IL 450 PVP gear.
Felt like all right i got single + meelee target down with that. Then i was OOMing on AOE Healing and then i find the best combonation ever for AOE heal and mana efficiency. As your healing you allready should have renew up on tank and i usually keep one up on the meelee in group too. So after those are refreshed and everyone needs heals spam Renew on the other three chars in group. Then hit Cascade, as it heals ur entire group it also refreshes Renew. This combonation can heal about 200-250k in 5 seconds to ur entire group and costs very minimal mana. Now Cascade is on a 30 sec CD, which means you need to use it at the right moment in the AOE damage coming out. Think of it as your O shoot the entire group is at or under halfway, hit that combo. That was my wonderful solution to AOE heals. With this combonation being used i never OOMed and was using my Shadow Fiend only on bosses. Still in 450 IL PVP gear.
At this point i was comfortable after about 4-6 runs and was now fine tuning this strat and getting gear ready for MOP raid. Jump into the future where i am at now. I am now running heroic dungeons and dont use any mana CD's at all and never OOM. I can even use PoM now with the extra mana and an occasional Prayer of Healing. I am feeling very comfortable about the Holy Priest and well i have done a couple of the world bosses and sat at 1st on healing meters with a nice gap, other than the occasional Druid who knows how to heal who puts me at second, but not by much.
I hope this helps those that are learning, i kind of explained my thought process on the whole progression to raid ready healing. I am curious how my mana will hold up in raids tonight and might repost my raid thoughts, but i am writing this because servers are down atm. Spirit or Intel we will see.
