Yes. Holy priests will rise. Just above the disc brethren, unfortunately. I join the bandwagon in questioning how 0% DA on PoH can be enough, if 30% wasn't enough when MoP was launched. Sure, 50% was too much. How about numbers between 35-45?
Rapture change is a change indeed and that alone will have to played out before I cast my vote. As the mana allows, at the moment, I do sometimes send quite few PWS's as a panic button. Terribly manainnefficient, but I suppose that's how Blizz wanted it to play out.
If these are to go live (given how often _most_ classes go straight from overpowered to dead last, I fear they do in somewhat similar forms..), I fear that I will indeed have two specs to choose from. That would be okay, but unfortunately both of them will be fighting for the last spot. Unless we have massive damage modifiers for atonement to be supported during T15. But is that more compelling play than actually SS'ing PoHs according to timers?
Here's hoping that the dev team will realize that these hits will make disc awful in raiding scene, and secondly, that while they will increase holy priest population, they will still not score much higher numbers than they currently are. As in, I'd wager them to beat disc, but disc will still have benefit of SS. Pretty equal between the two, just thousands behind the others. And that's what counts. I wouldn't mind playing either of the specs.
