EVERYTHING I've read basically says Rejuve is your 'go to' heal, and you should only be using LB on MT and OT (More or less). All the druids in my guild follow this mantra, as well as most druids I've PuG'd with, and this article basically follows that same line of thinking.
I disagree 100%. LIFEBLOOM is a my go to heal, and I only use Rejuve on the tanks, and sometimes on the raid if I expect AoE damage. Lifebloom is incredibly efficient, and costs very little mana. (782 mana per - 490 returned = 292 with only talents. 42 Less with Spark of Hope, Another 40 less with T7 bonus) None of your LB ticks will be wasted, it's almost always enough to get the person back up, and anything left over is handled by the bloom. I outheal the druids in my guild easily by 50-75% easily and doubling PuG'd druids healing , and unlike them, that's without me popping an innervate by the end of the fight. Overall I just find it much more mana efficient and an overall better heal. The thing is with the last patch, LB received a BUFF, because that 490 mana returned is static, anything that reduces the mana cost of LB, reduces it by twice as much now. (Previously: If LB cost 100, 30% reduction brought it to 70. Now: LB would Cost 200, 30% reduction brings it down to 140, and the mana return remains at 100 for a net cost of 40)
So... Why does everything I read state contrary to what I'm doing, yet everyone who does what I'm reading under-performs compared to me?
Note: Lifebloom accounts for 50%+ of my effective healing, to get a good idea how much I actually use the spell. Also, I don't actually have 2pc T7, just used that as an example of cost reduction.
