I have a WF Wiz, capped, and this is a much, much different build. Yes, you can heal yourself as a WF, and that is great, this build allows you to heal other (non-WF's), and to do so fairly well.
So far, I have been able to both CC, and help keep many of my party mates from dying. Better CC than a Cleric, worse healing, naturally. The fact that my heals come from the Dragonmarks, are impacted by Empower and Maximize, and cost no-mana is a very different version of a character to play in a party.
As I have only played to level 8 so far, I don't know how this will play at higher level. I am not in any way saying that it is "BETTER" than a WF Wiz. Having played Elven, Human and WF wizards, I would say that WF are tops.
However, I am saying it is different, a valid build, and fun.(so far).
