So with the proposed change to Penance:
Penance now also refunds 1.1% of the Priest’s maximum mana each time it deals damage.
How does that change our rotation? Make targetoftarget macro and only use it offensivly, even though it doesnt affect atonement anymore (as far as memory goes they are removing penance of the atonement healing)
Just gonna feel weird having one of our signature spells not used for healing. And a channeling one at that.
