Here’s my thinking: Lifebloom’s GCD is being reduced from 1.5 secs to 1 sec with Gift of the Earthmother for deep Resto druids. Its duration is also being increased from 7 seconds to 8 seconds with Glyph of Lifebloom (assuming this will be available to non-inscriptionists). Depending on the druid’s play-style, the way lifebloom works in BC allows for either 4LBs to be stacked (with no other spells being cast), 3LB + 1Rejuve, 3LB + 1Regrowth, 2LB + 2 Rejuve, or 2LB + 1Rejuve + 1Regrowth, assuming the druid is using every GCD to cast a spell while maintaining his/her lifeblooms. In WotLK, the druid will have the option to maintain up to 7 LBs at a time or replace any number of those with a lot of other spells. This may actually result in a much greater amount of healing output than we currently produce.

If Blizz had kept the effectiveness of LB the same in WotLK, druids would probably produce twice as much healing output as any other healing class, while also being able to stay on-par with aoe healing. Instead, we may still be able to do that, but now with added benefits, such as being able to refund mana/rage/energy/runes with Rejuvenation using the talent Replenish, heal for 30% more on a crit casting Swiftmend/Regrowth/Nourish/HT with the talent Living Seed, AoE heal with Flourish, and do not forget that with Master Shapeshifter and Improved Tree of Life, our overall healing output will be much higher (potentially countering the lowered efficiency of LB).

I’m excited about what we’re getting in WotLK, and the “nerf” on LB isn’t enough to bring me down.
