Ok. Wow.
As it stands now, based off all the blues so far, Resto Druids will just be incredibly, Stupid OP.
I ain't complaining, but I'm sure we'll get nerfed a lot before they go live.
In the first place, Blizzard has said their design goal is to have people sitting at half health a lot more, and mana will again be an issue. Druids have always been the most mana efficient healer, and always top any other healer by a lot the more damage there is. This is, as is.
Now add all of our hots are benefited by haste, without reducing their length, as well as crit. Now we got stupid OP. Then they added my favorite tier bonus, t8 as a talent.
Then Regrowth Crits (has a high base crit, pretty much guranteed crit on -25% people) sprouts a free aoe Wild Growth.
Our main problem as a tank healer used to be having to stop the heal bombing to refresh hots. Fixed. Nourish refreshs Lifebloom. That with Living seed, and our mana efficiency makes us a pretty damn viable tank healer. Also we'll have to stop the heal bombing to refresh Rejuv, but the chain casts will reduce the cast time of Swiftmend, so we can drop that bomb right after, as well as after any spike.
Mana starved in cata? I don't know how, +25% spirit, which we'll probably be stacking to start, and a free 3% mana every 6-10 seconds on top of that. Plus you might want to dust off your Idol of Awakening, thinking we might be using that for quite awhile.
Obviously we don't know what the mana costs will be, but even after they nerf us, just based off of what Resto Druids have always been strong in, (monster raw hps, + mana efficiency and healing while moving) coupled with Blizzards stated design goals I think every raid will want at least one Resto Druid, 2+ for 25 mans.
