What would you change for 4.3?

[HealMeNow]

A PTR is going up "soon", perhaps within the next week and we're going to start seeing spec revisions not long after. Following Kina's post about Holy's issues and the dominance, for what it's worth, of meters by Discipline, what's at the top of your list for tweaking?

For me I think Holy needs an overall buff of simple numbers to make up some of the deficit to Discipline, just as a start. Not a huge one mind, Holy isn't utterly terrible right now, but considering how similar the heal style is to trees you'd expect they'd be closer. One of the things you have to bear in mind when looking at a site like raidbots is that WoL doesn't calculate damage mitigation from talents like Inspiration and Barrier. If you do some simple math on your own logs you can see just how much that can be worth and as far as I can estimate it puts Discipline in the same ballpark as druids if good use can be made of Barrier. Only that leaves Holy even further behind, comparing the two specs.
The interesting distinction between Holy and Discipline is while disc has amazing tools if you know when and where damage is going to hit, if you don't, trying to fix it up afterwards can be a pain with the party limitation of PoH (and much reduced HPM if DA isn't used) or otherwise having to pick people out with Penance/GH. Holy isn't quite as clunky in those situations not least because of CoH being a smart heal. That's a pretty small niche to be good in with the way encounter design is right now, though, how much random raid damage did you find yourself scrambling to keep up with in T12 compared to the predictable bursts?
My favourite idea so far is to buff Holy's PoM when the player affected is standing in Sanctuary, gives you a better use for Sanctuary and more throughput at the time you likely need it most. Hell, you could make it a talent and replace the useless State of Mind while you're at it. Would take a little more work to implement than straight number tweaks but synergy between spells is a nice thing to have, makes a spec feel complete.

So what would you do? Would anyone just throw in the towel and ask for Renew to be much more like Rejuvenation?

edit: well, whaddya know, MMO-Champion have some notes up on the new PTR build with a Tranquility-esque Divine Hymn replacing State of Mind. Guess someone did throw in the towel on making Holy more like trees.

I am pumped for the Holy changes. It already looks like H Priest is going to be on par with Disc in a 10 man setting. 3 min DH? I'll take that instead of Barrier.

Also, the mana reduction to HW: Sanc seems like it will worthwhile to use in 10 man, possibly to the point of using it on only a few targets (i.e. your melee group or your ranged group).

Disc now is "Non-Holy." We shall rise again!

The changes all seem sensible enough, don't seem like they should be too OP. If this goes live I can be happy in my favorite spec without that 'maybe I should go disc' thought niggling at me. Still, this is early days, things may well change.

The numbers will certainly look better between a potentially more useful Sanctuary (I'll remain unconvinced on Sanctuary until we see exactly when the HPM/HPCT beats out CoH and PoH), Tranquility MkII and nerfed trees. I don't think it'll put holy over the top of disc, or even on the same level, partly because of int scaling but most importantly because in most circumstances disc's heals are functionally better, because DA and shields give effective health. Always (gimmick mechanics excepted) the further a player is from 0HP the safer they are, so that effective health is usually preferable to letting someone eat damage and healing it up after, as their health dips lower. The other thing is that those disc heals are heals stored ahead of time, allowing you to squeeze ten or more seconds of HPCT into one instant of damage through pre-shielding. Holy would have to be battering disc around on raw meter numbers before they'd really be on a par.

[Callu]

can't really see that having groups pre-DA'd via PoH is somehow superior to a quick reactive heal up with circle of healing and divine hymn on 3-min CD.

[HealMeNow]

Two parts to that.
Reactive heal v pre-healing. If you know damage is coming the same size preheal will likely be better because in the time between taking damage and it getting healed up, whatever the target's health is becomes their one-shot range. Baleroc is a good example of this, where a disc priest can heal all of a decimation blade strike through effective health beyond the tank's max hp to the point he could double strike like Chimaeron and the tank still wouldn't die. No other healer can give their targets that level of safety from burst damage. Some fights it won't make any difference and you need to be able to prepare ahead of time, but it's very powerful.
Divine Hymn. It's not live and we don't know what the numbers will look like. If it does the same as Tranquility and damage ramps up to expected last tier oh-god-it-hurts-so-bad levels, glyphed Barrier scales with damage and healing done while it's up, I think it'll be largely on a par. People are a bit wooly about the value of Barrier right now because the numbers aren't logged and WoL haven't done what they'd need to to calculate it for us. I saw someone over at EJ mentioned creating a tool to parse logs and figure it out and it's something that's crossed my own mind too, think it'd be useful to know.
But who knows, it's early days yet, I love disc but I wouldn't be sad to see holy be the star healer of 4.3.
