Tree of Life. Before Cataclysm, it was the Resto druid’s hallmark. Now it’s a super cooldown, the equivalent of the Hulk smashing out of his wimpy body to smash something. Even more so if you’re not running with the Glyph of No Thanks Pedotree. Lasts 25/31 seconds depending on talents.
Tranquility. With patch 4.1, Tranquility got a big boost for Resto druids. Instead of being a button you forget about, or hit accidentally and then curse, it should be a part of our toolbox that comes out every fight. Like Tree of Life, we want to time it to get the most use out of it. Lasts 8 seconds.
Right now these are our big cooldowns as Resto druids. There’s a lot of discussion over whether these are enough, since they aren’t particularly tank healing oriented or obvious life savers. Personally I really like them. I enjoy feeling like a Resto druid isn’t just interchangeable with a Holy Priest or Resto Shaman.
To get the most out of our cooldowns, we need to time them right. With the reduced cooldown on Tranquility we can use either of them twice in a raid fight, at least once in any instance boss fight. The cooldowns are short enough we can use them on trash without worry that they’ll be down when we need them. So when is best to use them?
First, any time you want to hit Tranquility, toss out Wild Growth first. The HOT will trigger our mastery and get more healing out of the spell.
Hit Tranquility when three or more party or raid members are hurt, or time it to go off with a big boss ability that’s going to do lots of AOE damage.
For Tree of Life, throw it in one of two situations: First, to straight up boost your heals. Second, if you’re running low on mana, pop TOL and throw Lifebloom around. When you get Clearcasting procs, toss out an instant cast Regrowth. Don’t waste your time with cast-time spells in this mode, or Rejuv, but do throw out WG as it’s stronger than it used to be.
I’m not a theorycrafter, I don’t do heroic raid fights and we’ve yet to down end bosses so take my advice for what it is, but here’s when I find myself getting best use out of both cooldowns:
Magmaw - Use Tranquility after a Molten Tantrum to get people up. Works beautifully if you’re using the all-stack-in-melee strat, still works if you’re kiting but you have to time it. Use TOL if you’re kiting worms or something else that requires movement. Remember if you’re in TOL and the head’s down and you don’t need to heal/regen mana, throw Wrath. It’s mana free in TOL and you might as well help out.
Omnotron – Use Tranquility when Magmatron does Flame Jets. Use TOL during Poison Protocol, especially if you’re being chased.
Maloriak – use Tranquility either during the red phase when the flame goes off, or during the green phase. We usually have more damage in red. Use TOL whenever you like but make sure it’s back up for P2. That phase can be movement intense and tanks can take spiky damage.
Atramedes – Time Tranquility for the ground phase at a point where you won’t have to avoid discs. Our raid stacks the ranged up in one spot so it’s great. TOL might be a good choice for air phase but honestly we don’t usually have much damage on that phase. Save it for spiky damage or if you get low on mana.
Chimaeron – coordinate with the other healers. You’re going to want to do both during Feud. I’d advise using Tranq the first time, TOL in combination with another healer’s cd the second time, and Tranq might be off cooldown the third Feud. Not really sure. If TOL’s back up in phase 2, pop it and use Wrath. You should be out of mana by then and you’re not healing anyway so go nuts with your tiny dps.
Throne of Four Winds – use TOL when you’re healing on the green/adds platform. Use Tranquility on the blue/ice platform during the aoe damage phase. If you’re on the wind platform, take a nap.
Halfus – pop TOL ten seconds after the pull. Keep people alive. When it fades, use Tranq after the Lifeblooms expire. That should get you past the damage intense part. You’ll have both back later so use them wisely.
V&T – use Tree on the second dragon. Tranquility can work for healing after a Blackout if another healer is dispelling and your timing is good.
Twilight Council – TOL in phase 1 at some point when you’re moving and there’s damage. Tranq in phase 2 after the raid gets hit by a big ability. Try to have both off cooldown for Phase 3. Blow Tranq first to get people nice and high, then use Tree to keep the fight going as long as possible.
