I have to admit that after my reference to wow powerleveling Nourish yesterday I was contacted by several very good raiding druids who told me I was out of my mind and that's it's a really good spell. When I asked them why so many druids don't like it, their response was that it's Flash Heal, and they want it to be something else.
So there you go. When I have healed as Resto, I didn't use Nourish much, but I should give it another look.
This is antecdotal data, and it's just as easy for anyone to say that they talked to a druid who said they can heal everything with Rejuv so Rejuv is OP. That is why we tend to be persuaded more by numbers (and even more by in-game numbers), but I do place a lot of value on the opinions of skilled players too. (Source)
On the topic of number of stats, as I said, you can play that card both ways. If you only need say spellpower, then it's relatively easy to just stack spellpower (warlocks were in this situation in much of BC). If you need lots of stats, it can sometimes be hard to fit the jigsaw puzzle to get them all (Prot warriors were in this situation in much of BC). As I said, there are advantages and disadvantages to both. We disagree that classes or specs who need fewer stats are at a competitive disadvantage or we would stop designing classes that way.
