Now, sure, its pretty good for farm content- its the most mana efficient HoT of all the druids arsenal, it heals for quite a large amount, and isn't that prone to overhealing given that it needs damage to work. And, unless I am mistaken, its the only choice out of all 3 that scales with haste, meaning that you can gear for it to give even MORE healing per use then the other two (Renewal scales with HP only, and is really useless for PvE resto. Nature's Swiftness scales with spellpower, like most heals, mastery, and crit, but not haste, whereas cenarion ward scales with mastery, crit, haste, and spellpower. Unless I am gravely mistaken)
But yea, its pretty good for throughput healing on fights where you don't need to worry bout tank deaths, or farm fights for HPS increasing.
