So your a tree! Your role in a raid is to heal pretty much everyone that is not the tanks. And to help out the tank healer(s) as needed. Your spells tend to be Heal Over Times (HoTs) but you have a few just plain heals and other useful buffs and debuffs.
Spells you have:
Rejuvenation: A HoT that lasts for 18 seconds, ticks every 3 sec, and (for me) heals about 2000 every tick. Instant cast.
Regrowth: A HoT that has an instant heal attached to the begining. It casts in about 1.5 seconds for me (with a buttload of haste) and the instant heal heals for ~5k (can crit for about 8-9k) and ticks for 1kish.
Lifebloom: A HoT that lasts for about 8 seconds, stacks to three stacks, has an instant heal at the end, and gives you back mana when it expires. Yes it's that confusing. But useful.
Nourish: A just plain heal that (when glyphed) heals more if you have more HoTs on your target. It casts in ~1 second (again with a buttload of haste) and I've seen it crit for about 10k.
Wild Growth: A HoT that can affect 5 targets within 15 yards of each other. Ticks every second, but the amount healed starts off at about 1k, then decreases with every tick.
Swiftmend: An instant cast just plain heal that can only be cast if you have a regrowth or rejuv on the target, and the glyph keeps you from consuming the HoT when you cast swiftmend. Oh SPOON! button.
I'm not going to bother with healing touch, because it's huge it's slow, and you are not a Holy Pally. And because I somehow speced out of having Nature's Swiftness.
Spec:
This spec is what my GM and I came up with. It dosen't include Celestial Focus, due to having enough haste on gear, and Nature's Swiftness got left out due to being the lesser used Oh SPOON! button.
As a hunter I was told "you don't really have a shot rotation, you have a shot Priority List." You basically go by what the conditions are, what's off cooldown, and "are you having to move?"
So this is the Tree Druid Priority List as of this point:
One or two people taking damage:
Regrowth--> Rejuvenation --> Nourish (repeat as needed) --> Swiftmend
Don't use Nourish unless a Regrowth is on someone.
If mutiple (more than 3) people are taking damage (ie a decimate):
Wild Growth ---> Regrowth (person 1)--> Rejuvenation (person 2) --> Regrowth (person 3)---> etc etc. -->Nourish and Swiftmend as needed
Special cases:
- Just use Rejuvenation if someone is taking just a little damage, but kind of regullarly (ie the little lasers in HoS)
-Lifebloom is great for when you can anticipate a lot of damage is going to come in at a certain time (ie decimate, pound), get it stacked and let it expire after the damage is done.
You also may want to put Fairy Fire on the boss (after the tank pulls!) if there is no other druids in your group.
Vuhdo: (My favorite addon EVER)
Set it up so it looks how you like it, I like class colors, HoT icons instead of just little colored blocks, and I have the swiftmend showing.
I got the great piece of advice to put only your instant cast spells on just plain mouse buttons (with no modifier) so you can heal and run, or jump around like a tard. When you press a modifier key to cast your spell (ie Regrowth is Alt+left click) you don't have to hold down your modifier key until the cast is done. Really! You DON'T!
Also keep in mind your vent push to talk key when deciding on your modifier keys. Clicking into vent everytime you have to decurse gets annoying after a bit.
That is basically it.
