The problem with Nourish goes beyond this. If you are wanting to play a reactive style resto druid for whatever reason, Nourish is not the talent you would take. It’s attempted (but failed) selling point is that it receives a triple benefit from mastery (this means you need to prep your hots to use it “effectively” - if you are casting it on targets with less than 3 hots, it is flat garbage compared to spamming regrowth).
Explanation - A lot of testing has been done on this, I’ll briefly give the recap. Regrowth’s instant heal vs Nourish with an average statline and three hots, results in regrowth doing more healing per cast time than Nourish, and only slightly less healing per mana (so, more healing for a very small extra mana cost). And note that compare does not take into account the regrowth hot portion at ALL, so any time the hot isn’t immediately overridden, will benefit regrowth even more, widening the gap.
If layering hots is your jam, going above 3 hots on a player will put Nourish ahead, but at that point CW is the better option.
Not only is it awful for all “playstyles” (it isn’t even fun), but for the competitive comparison it falls flat on it’s face… AND you’re giving up a talent for it… it definitely needs tuned. (But for me personally, is lowest of my concerns since I enjoy the other two talents on the row, just adding some addition clarity to the talent discussion)
