In Cataclysm, I pretty much boxed either Pally/4x Death Knight or 5x Druids.
The Druids were both Feral and Resto specs.



Almost all 5x Healer play, was as Alliance in AV or IoC.

As Resto x5, I had Rejuvenation and the Cleanse spell as clicks.
Control Clicks were less efficient but bigger heals: Lifebloom and Regrowth.
Alt clicks were more efficient, but slower casts: Nourish and Healing Touch.
Scroll Wheel Up for Swiftmend and Scroll Wheel Down for Wild Growth.
Tranquility was on round-robin, and I'd frequently tap the key every 10 seconds or so, for a long period of time with overlapping Tranquility going off in Drek's room.
Another take on boxed healing with Druids: http://www.dual-boxing.com/threads/4...TH-focus-macro

I would frequently: Rejuvenation > Swiftmend (which would proc AoE healing Efflorescence) > Wild Growth.
While the Efflorescence and Wild Growth were ticking away, the team was fairly immune to damage (when starting, a solo Ret or Rogue would solo the team; by the time they had 3/4 honor gearing in Resto equipment, 10-15 players did not have the straight DPS to kill them)...

I definitely missed having Tremor Totems...
Druids don't have much against Fear; just their Trinket.

Insect Swarm & Moonfire (x5 of each) on 3-4 targets, then refresh the AoE heals...
That would slowly take out groups who were attacking me.
Anytime I had a friendly DPS nearby, they had more killing power than my 5x healers did without cooldowns.

Starfire was superior to Wrath (excluding Tree Form), because there was no travel of the bolt/spell.
I could cast from down a hill, and take out a ton of players who did not know who was killing them.
The long road between Stormpike Graveyard and Icewing Bunker, with the short drop to the right was really good for that.

The only cooldown that made a huge difference for the Healers was Tree Form.
With Tree Form, Wrath casting speed made that quite a weapon.
At a choke point, like the alliance bridge in AV... during a Tree Form, I could drop 6-8 opponents with Wrath spam.

Druids have Stealth, which is huge...
They can bypass a lot of crap which others get stuck on.
They have Aquatic Form, allowing indefinite underwater play if you want.
Flight Form is instant, once they're out of combat.
