I start the fight with a regrowth on the tank + rejuv. I’ll likely throw a lb on him as he runs in. If I expect that there will be damage on the party I’ll slap a rejuv on them as well.

I then use wildgrowth on cooldown (don’t worry about overheal – this isn’t MC). I’ve gotten to a gearing level that I will use swiftmend on dps (or myself) and just use nourish to even out the tank’s health.

And I do use lb to smooth out damage across many targets if my mana looks promising.

I hate to call it a rotation, but would a good way of starting out a fight be to throw a regrowth and a rejuv on the tank, then throw rejuvs on everyone else?

Then use wildgrowth and swiftmends primarily for keeping the tank health up? And keep the rejuvs up on everyone?

Do you use Lifebloom outside of when you get a CC proc?

Don’t worry about threat – any tank worth their salt will be able to keep the mobs off of you. If you happen to draw aggro – you do have an aggro drop – shadowmeld is a great way to drop aggro. If shadowmeld doesn’t work then make sure you have barkskin keybound for some extra mitigation.

Let me know if you need more…

I think that, largely, I need practice. Healing a heroic is massively different from healing a hunter and his pet, which is all I’ve been doing for the last fifteen levels.
