I was blinded by excitement. For the past few months I have wished that Nourish was better, that I would be justified using it over Regrowth in 95% of situations. I've waited for this buff and I got so excited that I jumped to the conclusion that because most other things in the game stack and are multiplicative, and so must this bonus be. And it would be GLORIOUS.
But maybe it won't stack. And there's a compelling reason for it not to stack: that would keep us stuck in T7 for a while. Then again.. 2pc feral T6 anyone? So that's not exactly proof positive. Still.. it's a good reason to make the glyph an alternative to T7, not something that actually stacks with it. I don't think anyone wants to have to pass on shiny new gear because you need set bonuses.
If they don't stack, I'll definitely be disappointed, because T7+glyph would be great. But even so, things won't be so bad.
In patch 3.1, Nourish WILL be better than it is now. I WILL include it in my rotation.
Pre-patch, and with 4pc bonus, Nourish generally heals for slightly more than glyphed Regrowth. Now, normally, a bigger heal is a bigger heal, and you would logically choose the harder hitting heal (especially since it's faster and cheaper). The difference though is that I can walk into a raid with 70% crit on Regrowth and only 20% on Nourish. I don't often need a faster heal, I don't need to save mana, and the crit is abysmal. So it's pretty easy to see why I would use Regrowth over Nourish. But aside from my own personal preferences and style, there are plenty of people who have done the actual math and will tell you that Regrowth is better HPS (for the moment), and you need that 4pc set to even begin to approach glyphed Regrowth.
In 3.1 though, with the crit rate adjusted down for Regrowth and up for Nourish, Nourish will end up with 4% more crit through talents; 25% on Regrowth and 29% on Nourish (more if you have Natural Perfection). Regen will be more of an issue as well.
With HoTs loaded up and either T7 OR the glyph (assuming they don't stack), average individual Nourishes will hit harder than glyphed Regrowth does. They do that already of course, but Regrowth's massive crit pulls its average heal size up (and HPS with it). Nourish was always faster, cheaper (talented) and hit a little harder, but Regrowth crits so often that it comes out ahead. With the crit rates evened out in 3.1, Regrowth will no longer have this unfair crit advantage, giving Nourish a chance to get a foot in the door and meaning that we don't have to use Regrowth as our filler heal.
This is for tank healing, of course; I think raid healing will vary much more based on individual play styles. Tank healing has more of a rotation, whereas raid healing can vary greatly according to how different people approach it.
So - I'll still get my ideal rotation of HoTs+Nourish+Nourish+refresh+Nourish+Nourish+refresh (etc). Nourish will be cheaper, bigger, faster, and have a higher crit rate. The only proviso is that you keep 3 HoTs up to be able to make the heals worthwhile, but on tank healing this should usually be the norm.
Quick word on Living Seed - my thoughts
Also, regarding people getting upset about Living Seed now proccing a lot less (say, ~45% of the time instead of ~70%) - I think I prefer the changes. It will now work on ineffective healing, so rather than throwing a 9k crit heal and having it completely overheal and award a 0hp Living Seed, it would now (as far as I am following) award a 3k seed regardless of how much was effective heal or overheal.
Yeah, it'll be happening less often, but I think I would prefer a Living Seed that procs less often and is guaranteed to produce a seed, rather than a Living Seed that procs 70% of the time but is usually tiny or nothing at all because I overhealed (which is frequently the case). I have NO idea what the math on this is, maybe it will result in less HPS, but on spiky fights like Sartharion I cry when I see crits wasted and no seed awarded because my last heal was overheal.
Of course it also depends how many points we have left over as to whether I can take seed this time around; but I have found it to be valuable on select fights (like Sartharion, Patch..) and although it is situational, when it does come out to play I think it really helps. I don't rely on these procs, I see them as a bonus shield-type effect, so having them actually land consistently for 3k+ (instead of 500 or even nothing) would be great on these fights, even if it is happening a lot less often.
Whatever happens though
From a tank healing perspective, whether you have 4pc T7, the glyph, or (pleasepleasepleaseplease) both, Nourish will be improved, and I'm definitely looking forward to using it. With only one bonus it still doesn't blow me away with awesome, but bigger is bigger, faster is faster, and cheaper is cheaper. I can't ignore that. I've also never enjoyed "spamming" Regrowth; the idea of weaving Nourishes into my rotation seemed far more elegant, and it's what I've wanted since Nourish was announced.
Kugrette from Gnomeregan sums it up:
For the most part, nourish and regrowth fill a similar healing niche. Most players will use the one that is the strongest the vast majority of the time. If the strongest one is nourish, they will use it. If the strongest one is regrowth they will use it.
Until then, we wait.
As soon as anyone hears anything, you'd better tell!
