I don't have two pieces of T15 yet but I wonder if I should even bother taking the 4pc T14 out when I do.
With Atonement being my top heal by far right now (at least on most fights) I wonder if the 4pc T14 isn't a lot stronger than the new 2pc.
I tested my usual smite-rotation on the boss training dummy and got the following results using very similar items on the missing T14-slot:
with 4pc T14: 46-48k dps
without 4pc T14: 40-42k dps
Since the heal itself is a lot stronger than the dps I do I'd say that's around 15k hps I would be losing if all I heal with is Atonement - or even more.
And that doesn't even count in that more casts of Penance = more chances of sniping low-health players & more chances to quickly build up stacks on the tank for Prayer of Mending.
Now, what would I get with 2pc T15?
I'm raiding 25man if that matters. I'll definitely use the 4pc T15, but is the 2pc even worth changing to?
