The 2-piece is regen-only, not the most exciting thing in the world, but gives a pretty reasonable amount of mana.
The 4-piece is tricky to evaluate. It really only does anything in Tree form, but has the potential to make a bunch of rapid Lifebloom blooms around the raid be pretty strong AoE burst. It's interesting at any rate, and should at the very least be nicer to have around than then pretty worthless T11 2-piece it replaces.
Tecton, this is based on your 4/27 version with the added ZA gear (I still have to put that in the OP at some point).
Quick sheet update for PTR notes, as usual.
--Mastery change (all I did was change the conversion ratio and increase uptime to 100% on everything). Will refine things somewhat if this one goes live. But assuming people maintain 100% uptime, this will be a perfectly good estimate (if you want to examine lower uptimes, just reduce the percentage on all HoT's for now).
--Removed Innervate swapping.
--Mana Tide nerf.
Mastery is likely to be very strong (beating out even the new crit, although at least crit will be close now). Might be trickier to weigh mastery against the benefit of haste plateaus.
Here's a small revision to that with a simple mastery uptime option for people who want to play with it. The "Harmony uptime" parameter controls the mastery application to Rejuv/Lifebloom/WG, while Nourish/HT/RG/SM are fixed at 100%.
Trinkets added, including estimates for Eye/Jaws. Also, TreeCalcs now has the haste overhaul that WrathCalcs got a while ago (i.e., it actually computes all HoT breakpoints independently for all temporary haste buffs and then averages them together). I figered I'd add it in here, since we're likely to be using Shard of Woe for a while, and in general there are a lot of gearing issues surrounding haste breakpoints.
Still need to throw the Nourish bonus in there in some way.
Put an update on the main thread with the WG fix. Also added a socket to Flickering Shoulderpads, deleted duplicate Flickering Shoulderpads entry, and deleted Flickering Wristguards (since it can't have Int suffixes).
