Tree of Life?

I boosted my character, but my Tree of Life form is not there?
I've been to lazy to ask the forums, but here I am.
Seriously, someone help me.
Has anyone else had this problem too?

Tree of Life is disabled ever since Cata and no longer exists as a shapeshifting form that gives you a healing boost. You can still look like a tree with the Glyph of the Treant which allows you to shapeshift in the old tree form but no longer gives you any healing boosts. However if you choose the talent called Incarnation, you can use improved tree form which turns you to an improved treant and boosts your healing for a time.
