25 warden seeks helpFollow

I've gained some excellent advice here, so sorry if I ask for more.

My little warden is now 25 and for fun I put all my points into the ability to charm animals (in WOW I played with pets and I like to use them).

I'm a little worried if this is the right thing to continue with. So, for the Wardens here, what should I spend points in, if not all in the skill to charm animals? Will I need to worry about improving my healing for groups, or could I wait till later levels?
