Healer/ Support mage?

[Ozwald]

I've always played a healer or tank, The warrior has the tanking covered but is there a viable build for a "healer". I enjoy playing as a support class more than just face melting. Personally I find reward in allowing the dps to do what they do best hence my starting this thread. My questions are as follows.

1. Is the mage a viable contributor to a group as a "supporting role"?

2. Does the mages healing allow other classes to focus more on doing damage and not so much on self preservation?

3. What would a possible build look like as I have only really played my warrior up till now. (mage is lvl 9)

4.Should I seek psychiatric evaluation for having these thoughts of turning a face melting class into a robe wearing sandle toting vw microbus driving hippy healer?

Any and all input is appreciated, Keep in mind that this is an honest set of questions not some troll. I have always found the community to be any games strongest and best asset which is why I turned here first.

Thank you all for your time.
