It caps at 50% without germination, and you'd be casting up to x rejuvenations you may not even need (i.e. those targets do not require healing to begin with) just to trigger the effect, at which point you'd be outright be better of to waste the mana on regrowth to begin with. Not that you'd waste mana in 5+ on regrowth anyway, if you can just opt for MoC there (or: CW+ Flourish). Honestly, about any other combination of talents yields a signifcantly better option than Abundance, even if it's merely because it is signifcantly less restrictive in use (well, though usually it's not only that, but also provides significant throughput advantages).
It's gonna yield GCD clipping, and that just plays incredible bad.and even at 7-8 stacks its fine, its still okay spot healing with 0.2-0.6 sec cast time, closer to 0,8-1 sec it starts to become weak.
That's because Inner Peace inherently is rather weak given the current state of raid CD's.
The problem is, as I said above, any other talent combination is signifcantly less restrictive, and will yield superior results.or Spring Blossoms is simply not wanted. And even though Abundance is just as bad (don't mistake this for a defense for this horrible talent, because it's lame), it'll be a go to talent for people due to it's utility.
I don't see why PvPers should have >1 talent tree available to adapt their gameplay, and for PvE we're going to be stuck with a single talent build. Sorry, but if a talents only use is in PvP, put it in the PvE tree. If there's no room for it there - especially if it's because all option theres are better - then you really should ask the question wether this talent is any good to begin with.I'll once again bring in the PvP crowd; that will look at this talent for a minor, yet noticeable throughput increase compared to the alternatives (especially now that it doesn't compete with ToL / SotF anymore).
You can claim that "that's what the pvp talents are for" but that's a completely irrelevant argument, as PvPers (and certain small group PvE'ers) will have to choose talents here as well.
Even if it somehow became more popular than Abundance (doubtful compare e.g. the SoO set bonus, you simply do not need that many direct heals to begin with, even in 5's, as you procede along a strict priority in spells - which can be further skewed in favor of other abilites by less restrictive talents), the swap still has some severe implications on T75, i.e. Cult triggers when you'd use ToL, yet has no uptime restriction, provides higher throughput due to an additional mastery stack and both for a large fraction get their value due to the same spell (high trigger treshold all hold this problem due to the mastery stack being essentially permanent then, and at low values, you hardly ever get use out of the talent, as that's a state you ideally would not want to see that often).I think you'd be surprised how popular Abundance might become after they swapped it with cultivation.
So in a best case, they didn't change anything, slot 3 on T75 is still dead, and T75 still has the same option, to the more likely outcome I think is: T75 -> Cultivation, T90 -> SB, that is they eliminated choice. Fun fact: the culprit here isn't so much the talents in question (well it partially is for abundance), but how this thing called Harmony yields significantly higher value on certain talents, than it does to others. I don't see this changing, unless those talents get turned into "counts as 1 mastery stack" (and that has some severe implications on how those talents perform on a high haste/low mastery build ...)
