Hmmm, So I forgot about Beacon. I have been using that for the melee toon, and not the tank. I read somewhere that the beacon cant grant the 50% if you are healing itself. I think it was a blue post too. Ill have to see if I can find it.. Course it may be old info.

Ive not been using the holy power, Nor have I been using the Judgement spell.
I typically keep the tank in Concentration Aura, unless I hit a particular nasty boss and need Resistance aura. Is that the right one for the judgement to return mana?

I also typically keep up Seal of Insight, however the healer isnt hitting anything with melee.

Im gonna take this advice and do some tests with the beacon and the judgement. Perhaps that, and respecing a little may help.
