Maybe this should be in the Healing Discussion, but the crux of the post is about Haste Values and Nourish Clipping.
I'm currently looking to move points out of GotE, probably down to 3/5, and to reach 3/3 Celestial Focus with a spec like
18/0/53. To keep a 1.0s GCD on HoTs the OP suggests 606 Haste Rating is required (raid buffed), which is easily obtainable assuming all non-set items have Haste rating instead of Crit, whilst still maintaining the standard amounts of SP/Regen. I'm around 580 Haste right now with a Crit Amulet equipped (Armoury is down for maintenance, but its Relinor, Arathor realm).
The sense behind this spec is to have Nourish cast as fast as possible without relying on Nature's Grace, hence reaching CF. I lose one point from Revitalise, but I don't value that Talent much, and one more point from Tranquil Spirit when I don't currently have mana problems.
My main concern is:
Given nourish is around 1.1s casting speed at 616 Haste and 3/3 CF. When NG procs and Nourish hits a 0.9s cast speed, will it actually be detrimental because it will interfere with the spell queuing? Both these casting speeds are according to Quartz cast bar, in-game with a WoA totem and Imp. Moonkin Aura in my group. I assume these numbers are rounded up/down from a more exact value.
If NG is detrimental, it would be possible miss it and waste four points in Brambles + X to still gain CE. Feels messy, but two of those points have come from the redundant GotE anyway.
I realise spell queuing and clipping Nourish was discussed a couple of pages back, but there did not seem to be a definite conclusion, or a cast speed mentioned where the spell queuing certainly becomes a problem. Possibly at 0.9s it is not a problem, I don't know.
Secondly, when getting to hardmode encounters, am I likely to want more points in Tranquil Spirit? To achieve this I can drop Revitalise all together, or admit defeat and not reach CF. I expect that a Meta Gem/Trinket change will have more impact on mana regeneration than Tranquil Spirit anyway.
Finally, the reason I am looking at CF at all is because I do not value the other options for the spare points, namely Revatalise/Nature's Perfection and Tranquil Spirit. I consider CF at least as a clear way to increase healing output, or the speed of our basic upfront heal, which may occasionally save someone from a close death. Should I value one, or all of these other options as more beneficial than the 'wasted' points achieving CF and its effect? Personally I would much rather have a strong end-tree talent that we'd definitely want to spend our points on, but I guess you have to make do with what you're given.
