- Gift of the Earthmother (Tier 10) changed to reduce the base global cooldown of your Rejuvenation and Lifebloom spells by 4/8/12/16/20%.
- Tree of Life (Tier 9) increases healing received by 6%. (Previously 3%).
- Improved Tree of Life (Tier 9) now increases your healing spell power by 5/10/15% of your spirit while in Tree of Life Form. (Previously reduced the mana cost by 5/10/15%) :
and it seems like a huge nerf to me.
what concerns me most is lifebloom and wild growth. so wild growth is nerfed from 1600 to 350 (!) healing over 7 seconds. ofc, scaling would be most important here but i doubt blizz increased coefficient here. so basically we are left with 51-point talent that heals for less and during longer time than priet's coh?
as for lifebloom nerf - question is how much more does it cost and how much less does it heal. on ptr yesterday lifebloom was healing ~8% less than on live. so much more did they nerf it?
as for tree of life change - its nice that bonus healing was increased from 3% to 6% but why remove reduced mana cost effect? they just changed tree completely removing everything it has now and giving something else. i dont like such changes.
i like gift of the earthmother change tho, which reduces global cd even more but still...
we have lifebloom and wild growth nerfed badly. i dont see how wild growth can be competitive vs other aoe heals.  i dont even think i would include it in my talent tree. we can keep more lifeblooms in raid but their hps get significantly nerfed. so how i see it now is that either druid will be single target healer with nourish / regrowth (still less efficient than pala) or will be hot bot designed to keep lifebloom on 10 ppl in raid providing support for raid healing.
