The Enigma Order

Lifeblooms and exploiting.
While technically, this is probably not considered an exploit, it so heavily warps healing comparisons between classes, that it should be. It is, however, in NO WAY unintended, or frowned upon, or disliked, or anything negatively. One could even argue that it is what makes the druid class viable in healing Endgame - and I would agree with that. Exploiting Lifebloom is done by using Trinkets with Use effects that add healing done. The most commonly used is the Essence of the Martyr ( http://www.wowhead.com/?item=29376 ). Other trinkets are Heavenly Inspiration ( http://www.wowhead.com/?item=30293 ), Warp-Scarab Brooch ( http://www.wowhead.com/?item=27828 ), Oshu'Gun Relic ( http://www.wowhead.com/?item=25634 ) and Zandalarian Hero Charm ( http://www.wowhead.com/?item=19950 ). Generally, these items can be used at the same time. By using these trinkets before applying your Lifebloom, the first lifebloom will gain an unreasonably high amount of +Healing (I can reach 2350 for example). As Lifeblooms depend only on the first stack and how much it ticks for, when it comes to stacking multiple Lifeblooms, if you restack it, the 2nd stack will also have the same high amount. However, if you keep the lifebloom rolling, it will also maintain the same high amount of healing, EVEN IF THE TRINKET BUFFS EXPIRE. You are essentially using the trinket buffs all the time, even when they are on cooldown.

idol
Use the right idol is something I cannot stress enough. Each idol available gets you an additional 2-3% on all healing spells you can use. Harold's Rejuvenating Broach ( http://www.wowhead.com/?item=25643 ) also buffs Swiftmend, if you are using it on a Rejuvenation spell. You should macro switching in and out of Tree of Life form, and equipping the right idol when you do. As for generally switching idols, make sure you do it while in a global cooldown from casting a spell - that will make sure that switching the idol does not itself cause global cooldown.

ToL
Use Tree of Life aura as a tool, not as something you paid for but want to return. It has its uses. Find them. For example, it is a great aura on Gurtogg Bloodboil, or High Warlord Naj'Entus. There is also an exploit for the ToL aura (tested 2.1.3). This is how it works: Upon switching, your total spirit is given as base value for the aura. If you do not switch out, you can maintain this base value for the aura, and can change gear in order to exploit your tree of life Aura. However, any spirit above this base value that you gain while still in ToL, actively updates the aura (increases it). When this temp buff fades, you are returned to the base value of the aura. Note that, for Lifebloom rolling, the ToL aura actively updates the spell only as long as ToL is active - once you switch out, or they lose the aura, there will be a reduction to your Lifebloom roll. Entering or exiting combat has no effect.
Note This trick is under dispute:
