Priest spec, Holy

Is this tree what I should be using? Wondering if my current spec is a good one or if this one is better.

Thoughts?

My Holy priest has a spec very similar to the one you are running now, with the exception that i take Inner Focus and have a few other points placed in Holy. I've ran with my build for a long time and he was an effective main healer in Uld10 back in the day(before i stopped playing him).

As for the other spec you linked, it looks more like a hybrid spec as a lot of the talents points are put in defensive places and are not buffing your ability to heal. 5/5 points in Spell Warding, instead of 5/5 points in Devine Fury is a prime example. Spending points in Spell warding will reduce DMG received by you, as to where Devine Fury will allow you to cast your heals faster.

But, at the end of the day it is how you wish to play your healer and the spot you want to fill.

Add-ons are important too. I still use healbot, although I've heard good things about Grid. I got into the habit of casting PoM first on the targetted tank, and binding renew and flash heal to right and left mouse keys. Use Circle of Healing liberally and any time any players other than the tank are taking damage. Pop PoM every time it is up. If you don't have a disc priest in the raid or need more OOMPH as a tank healer, use shield as well.

Dazzit. You should see your numbers double pretty handily.

Took me months to spec BACK into circle of healing.

Never used Healbot, and i swear by Grid. Once you get it configured for how you want, it's stupid easy to see who needs healz, who is getting healed by someone else, and who has aggro to see who is about to need healz.
