Glyphs for raid & tank healing

All “major” healing glyph analysis:
Glyph of nourish: Nourish heals for 6% for each additional HOT on the target. If you are doing any MT healing at all, you will use this glyph for the benefits outlined in section 1 of this guide.
Glyph of Lifebloom – Increases duration of lifebloom slightly. Good if you are planning to roll lifeblooms on your target, to reduce the amount of mana it costs you.
Glyph of Regrowth – Increases healing done by regrowth if your target already has the regrowth HOT on them. This used to be my MT healing glyph. However, I’m replacing it in 3.1 with the Nourish glyph
Glyph of Healing Touch – Only okay to use if you don’t have nourish yet, in which case most of this guide doesn’t apply to you in the first place.
Glyph of rejuvenation – Requires target to be below 50%, so it’s mostly useless for now.
Glyph of swiftmend – Swiftmend doesn’t consume your HOT when you cast it. Nice to have if you’ve gotten the 2-piece set bonus that increases swiftmend’s healing done and/or you are using swiftmend a lot.
Glyph of Wild Growth – Increases the # of people healed by wild growth by 1 additional target. Great for healing a group of melee, assuming you have 6 people that this would heal at one time.
Glyph of Innervate – Increases the effectiveness of your innervate spell. Use this glyph if you are having mana problems. (At level 80, the glyph adds and extra 3146 mana to you, and no longer scales with spirit or any other stat).
