Lifebloom is another powerful (mana-hog) spell unless it blooms.
Have you read up on your Druid changes? Haste cap is where you want to be, and glyph your rejuv. FYI: The T9 Boomkin gloves are better than the T9 healing gloves for haste. I'm not sure I'd ever gem a pure blue, I'd think you should gem spell power, haste, and spell power/spirit (purple) in blue sockets. I can't have a look at the spec yet, but if you want some extra haste dip lower into the balance tree for the haste talent until you can re-spec out of it.
