Resto Druids are getting some more nice buffs in 5.4 and they are currently looking like the OP healer for 5.4. One of the major changes is to their Wild Mushroom healing spell.
First, the healing and spell power scaling to wild mushrooms has been tripled (yes, tripled). It goes from 4,446 healing plus 41.4% spell power to 13400 plus 124.2% spell power.
Mushrooms can now be moved without losing the accumulated healing on them, which will be great for fights like Heroic Magaera, where the stack point could be messed up with cinders and/or ice, and the raid leader calls for the raid to stack on a different mark right before rampage. Now a druid can simply move the mushrooms rather than losing the healing or having to wait to bloom the mushrooms.
However, the mushrooms can no longer crit heal. And it accumulates overhealing done by Rejuv by 100%, down from 150%.
The mushroom is now a single mushroom, rather than the group of mushrooms currently used.
Here is the full description:
Wild Mushroom (New)
Grow a magical mushroom with 5 health at the target ally’s location. After 6 sec, the mushroom will become invisible. The mushroom grows larger as it accumulates healing power from 100% of overhealing done by your Rejuvenation, up to a maximum of 200% of your health in bonus healing. Recasting Wild Mushroom will move the Mushroom without losing this accumulated healing. Wild Mushroom: Bloom can consume your Mushroom to heal nearby allies. Only 1 mushroom can be placed at a time. Can be cast in Tree of Life Form, Moonkin Form. Druid – Restoration Spec. 40 yd range. Instant.
Mushrooms have been popular for druids that actually remember to use them, and they can be a huge amount of healing when positioned correctly. But now that these can be repositioned, they will become a very important spell in the resto druid toolkit.
As always, things can change on the PTR between now and 5.4 launching.
