I'm currently a single class druid (only level 14 :P ) and have been considering taking cleric (and eventually replacing it with healer and dropping the cleric levels with the quest) for the extra heals and the 'Healing Adept' line.
These are listed on gamersinfo.net as masterable abilities, and I'm wondering if the '+x-x heal' affects the druis Heal-over-time abilities and spells such as Growth, Regrowth, etc, and if so, is the bonus applied to rach of the small heals of these spells?
