Best group makeup for MT group?
We've been finidng that the best group for the MT in a raid, in fights except for those that are the most aggro sensitive, is generally:
Lock w/Improved Imp
Pally w/Improved Devotion Aura
Or alternately, replace the lock or pally with a third tree druid.
The tree druids wear full spirit gear (even green 'of spirit' things) when they enter tree form, since that sets what the healing benefit of the treeform will be! Then they swap to normal heal gear before the battle starts.
Then when it starts the druids use a heal trinket and stack 3 lifeblooms. Then they cast lifebloom repeatedly, never letting it fall off. Refreshing the lifebloom will cause it to give the amount of healing it did while trinketed! In between these lifeblooms they can cast other spells if needed, but often dont need to.
The effect of 2 or even 3 tree druids, with +heal auras that were based on insane levels of spirit, with 3 lifeblooms each that were started with a +heal trinket, is insane. It gives the MT several thousand hp of healing per SECOND, absolutely every second. In addition to normal heals coming in.
The pally armor buff and imp buff dramatically increase effective health.
We're finding this strategy to be rediculously good.
