So something to consider. I initially thought I could use Resto Druid to throw out Wild Growths at my Tank and because it heals up to 6 Targets it would hit the Pets as they are closest. However it never will heal Pets only other Players unless you cast the initial cast on a pet and then the other heals will still goto players.

Chain Heal on the other hand will happily heal pets and it will heal the ones that have taken damage. All the Totems seems to also heal the Pets as well as your whole group.

While it sucks the initial heal of Spirit Mend got nerfed the real benefit to us I think is the rolliing HoT always on your Tank with 100% uptime by stacking three hunters. Taking a bit of the pressure off while moving or using a more 'group/raid' focused healer like a Shaman as their biggest complaint seems to be tank healing.
