Once you have the gear, 5-man dungeons (heroic or not, it doesn't matter) become extremely tedious. Rejuv on the tank and just spam Wild Growth. Yeehaw!
Looking at your stuff, you're moving in the right direction. I'm noticing some +hit gear there, you're probably transitioning from leveling gear to pure healing gear, so it's cool, though. Basically, just get stuff with haste, intellect and spirit on it. Stamina sort of tags along on all gear that isn't green, so don't worry about that.
Haste lowers your GCD which is very important for Rejuv spam in raids. The lower GCD, the more Rejuvs you can cast out before you have to start over, increasing your HPS. Crit is useful if you're 4pT9 (because then Rejuvenation can crit), but if you're going pure raid healing (which you usually are since people love Paladin tank healers), you're better off not stacking crit. Get your spell power up, get your mp5 up, get your haste up and you become a beast.
I think I forgot to mention that mp5 is pretty awesome earlier on. Yeah, you want mp5, because you'll be spamming Rejuvenation non-stop and while Innervate does give us the equivalent of a Healadin's Divine Plea, we lack the massive intellect pool of the HL Healadin, so we don't get
as much out of Replenishment. With the right trinkets and enough spirit, you basically never run out of mana and you can just spam that Rejuvenation button while you sip your favorite alcoholic beverage.
Taking a look at your talent build, you would probably gain more from losing:
Natural Perfection
- Crit is not really useful for anything except tank healing, which you won't be doing much of in raids, and you can survive without the crit in 5-mans anyway since Nourish is such a crit beast.
Improved Barksin
- PvP talent.
1 point in Living Seed
- You really want to only go 2/3 in this one, because if you find yourself in a position where you have to spam Nourish (only case where Living Seed is useful), you'll find that your beast Nourish crit rate will keep this nice little thing up nice enough. One point better spent somewhere else.
Instead I'd get:
3/3 Revitalize
- Godly in 5-mans as you should be positioned between the rDPS and the mDPS, causing everyone in the group to get hit by the spell. It increases your mp5 considerably.
Empowered Touch
- You can get this for early 5-man healing, since you'll probably use Nourish a lot.
Improved Tranquility
- Highly underrated talent. Reduces the cooldown on Tranq to 3 minutes or so and enables you to use it whenever you want, because you won't pull huge aggro (0% aggro gen when maxed).
Looking at your glyphs, you should replace Glyph of Rejuvenation with Glyph of Wild Growth and add Glyph of Swiftmend to the mix. Swiftmend is going to be your "Oh ****" button in most cases. Having it not consume a Regrowth or Rejuvenation will enable you to use it more freely, especially earlier on.
Glyph of Innervate is a nice touch. I roll with it as well, primarily because I'm lacking a bit of mp5 and because it enables me to use Innervate on others and still get some myself. Sharing is caring, y'know?
Some people might advise you to get 3/3 Celestial Focus for that extra haste, but I've tried it and I really don't think it matters until you start end-game progressive raiding, in which case you'll be close to haste cap anyway, lul.
It's a good idea to get the ilvl 245 idol fast. I believe it gives you something like 200 SP as long as Rejuvenation is running somewhere, which it should almost always be doing. You can opt to go for the ilvl 264 one instead, but you might want to save those EoF for T10 (since we love the 2p bonus, yes we do).
Anyway, you're familiar with EJ and their Resto guide is pretty solid, so I'd say you're all set. Going to be a change to go from a direct healing class like the Paladin, where you have to be casting something almost constantly, to an on-the-run healer like the Druid. Those 20k bombs aren't going to happen much, but the increased mobility is a worthy trade-off in my opinion. Being able to run and heal at the same time is just epic fun. Especially the survivability given when you roll 3x Lifebloom, Rejuvenation, Regrowth and spam 1s Nourish. Hell, rolling the three HoTs alone is enough to keep most people up through some serious focus fire. I've healed a Frost Death Knight who tanked in DPS gear by using that technique alone. The constant flow of healing means you will be keeping people topped off more than on your Healadin. You don't wait for them to drop before you throw a bomb, you throw up those HoTs as soon as possible, because once they start dropping, you're in a world of pain.
That's why you need the Swiftmend glyph! It's the closest thing to a Holy Shock bomb you'll ever get.
