yeh can cast all the healing spells in tree form before the patch yeh weren't able to cast Healing Touch in tree form and some other ones cant remmeber.

But I never use healing touch since yeh can burst out huge healing with Lifebloom ,Regrowth ,Lifebloom,Rejuvenation, Lifebloom,swiftmend,Rejuvenation
add Glyph of Rejuvenation and a pali tank with ardent defender and improved devotion for another 6% to being healed.

been debating on trying moonkin also
