Nourish would be amazing, especially with the 4 piece t7 effect habbo taler but it's just overshadowed by re-growth. It is a faster cast time, and lower mana cost, but the fact that you have to have every hot up on the target to make it effective, we really don't see it as viable as re-growth. We will have to research this further. Rejuvenation likes innervate or click trinkets, it heals for 1300-1500 without the glyph every 3 seconds, nothing new, but with the crazy mana regen we have, we choose this over many other options for raid healing.
