Since WoTLK Holy has played second fiddle to Disc. Do you think Blizz will use the retooling in Legion to finally make Holy a decent choice again, both in the minds of players and in actual numbers?
I am skeptical... and with good reason. Absorbs, Disc and Holy have been out of whack since WoTLK. That's 2008... 2000 frickin' 8. That's a loooong time for Blizzard to figure out a solution the absorb problem. If, in my hopeful, naive mind, they've been working on a solution for seven years, I really hope to see it in Legion. The realistic and pessimistic side of me thinks, that, if in seven years they haven't done much to solve the problem, it's because they really don't care. And the well-medicated conspiracy theorist inside of me thinks "They probably realize Holy Priests are such a tiny fragment of the population and thought about so little by other players that they can be forgotten about and no one will really care."
And just to be clear, it isn't that Holy is inherently bad. In the hands of the right player it's an incredibly poweful spec. I find it to be an absolute riot in casual PvP.
But for the everyday player, which is the group I am included in... the problem is that it's just not as good as Disc. Given that absorbs will always trump raw healing, it comes as no surprise that Disc came out king over Holy.
...But wouldn't it be great if Holy and Disc finally found some balance with each other? If absorbs were controlled a bit, but not enough to kill the spec? It'd be nice, as a Holy Priest, to actually be let into raids and PVP without having to think "God, how many people are going to harass me until I spec to disc?"
