Agreed about cocoon. Also, I think party healing could use toning down as well. For a Cleric (or FvS or Druid) with 700 Positive Spell Power (easy to get), one heal will do 1200 hp of healing. One Cure Serious Wounds (with no Max CL) would do about 360 hp in healing.
For Cleric healing, I would like to see some more interesting healing spells added, as well as a revamp of Divine Disciple to make healing a bit more interesting than spam MCSW and MH/Heal. Possibly decrease healing numbers a lot, but give Divine Disciple a casting speed bonus to healing spells, and a SP cost reduction. So less healing, but faster. It (hopefully) would make healing interesting/challenging.
