I have been thinking about this a lot today, wondering what can be done to improve our Mastery given that it will only scale with PW:S and DA. Awesome changes to PW:Barrier on Beta by the way, loving it.
PW:S...the spell we will not be able to afford using as much as we do on Live, for this reason I feel Mastery should be re-worked.
For me ideally we need something similar to that of the Paladin Mastery http://cata.wowhead.com/spell=76669/illuminated-healing,
For example, Tooltip:
Your direct healing spells also place a Divine Aegis shield on your target for 10% of the amount healed lasting 8 sec. Each point of Mastery increases the absorb amount by an addtional 1.25%.
This will bring us back to Mitigation Proper and give us a reason to use Mastery, afterall we are the true mitigation healers in the game. Paladin Mastery is: Illuminated Healing, Holy Priest Mastery is: Echo of Light, Disc Priest Mastery: could be called 'Renewed Hope' ? ...
Any thoughts ?
