For Tier 2 I completely agree. With mana being much tighter I feel the free spell from NS is very beneficial. CW just doesn’t feel very strong to me and we all know Renewal is a waste in comparison.

Tier 3 is like you said, completely up in the air. FS probably won’t be great because the need for a ranged snare is really never needed. ME might be interesting for add control depending on the fight. Typhoon has already proven to be helpful with certain fights (Rag).

Tier 4 is a tossup between Soul of the Forest and Incarnation. Soul of the Forest is most effective in combo with Wild Growth (unglyphed) and it results in a 30% increase in it’s healing. Soul of the Forest actually brings WG back to 4.2 potency, but at the expense of losing Tree of Life. I’m not sure if it’s worth the tradeoff. In my testing I found Soul of the Forest to be really powerful in Heroics for handling burst (and I imagine it will carry over into 10′s as well) especially if you dislike the new healing shrooms mechanic. Force of Nature is still really terrible.

For me Tier 5 is again completely optional. I’ll probably take Ursol’s Vortex for another “kite the adds” ability to help out the tanks if needed.

Tier 6 I’ll be taking Nature’s Vigil. Before the nerf Dream of Cenarius was actually very powerful. Unfortunately, the healing benefit has been nerfed so much that it no longer outweighs the HpS loss of casting Wrath. Heart of the Wild just seems like a stat booster but I feel having another personal throughput CD is much more valuable.
