I spent some time testing out Nourish on the PTR. I have slightly out-dated gear on this copy, so I’m having to use all 10-man set pieces to get the 4-piece T7 bonus. That in mind, even with only 1845 + healing, nourish is starting to look pretty good with the right supportive HOTs. Basically, this is what nourish was healing when I cast it on myself more than 10 times at each level, with 1845+healing:
At zero HOTs, nourish with my gear is lack-luster: My “hits” (non-crit) ranged from 3840 to 4176.
At 1 HOT (regrowth), nourish jumped up over a thousand healing: Ranged from 5074 to 5361.
At 2 HOTs (regrowth +rejuv): Ranged from 5434 to 5882
At 3 HOTs (regrowth, rejuv & lifebloom): Ranged 5867 to 5364
At 4 HOTs (regrowth, rejuv, wild growth & lifebloom): Ranged 6407 to 6749
Lifebloom only counts as one HOT, regardless of if you have 1 or 3 stacks on the target, so the max number of HOTs is 4. Having 2 or 3 HOTs is more sustainable for single-target tank healing, as using wild growth as a tank heal is a gigantic waste of mana if it’s only hitting 1 person.
However, with 4 HOTs, my highest crit with nourish was 10,123. I almost felt like a paladin, only the challenge of keeping up 4 HOTs just on myself was a lot more fun than just spamming one button, lol. Keeping up just our three single-target HOTs and using nourish between HOT applications looks like it will be pretty good in Ulduar. It’ll be sad having to give up the T7 combination in favor of the rejuv & swiftmend set bonuses. I may not be willing to give up the T7 4-piece bonus until I have the 4-piece T8 bonus (for awesome rejuv raid healing). For direct heals, nourish definitely outshines glyphed regrowth now.
And these tests were all at a pretty low level of spell power, without raid buffs and such. For tank healing, as I talked about before, you can use HOTs to buff your nourish. Nourish won’t be that useful of a raid heal on it’s own because of the HOT requirement.
