I tried this one and Templar and Cleric. I couldn't heal for crap in nub plate. They were pretty durable though.
Under defense the Boastful Roar was ridiculous chain damage did a 2600 damage in my teens. I did less damage when I took defense off for cleric but seemed tankier.
The last build I did was a demonologist to try out some dps. The bubble you get from witchcraft was op against mobs.

I only played up to high teens and low 20s over open beta, maybe someone else has more experience to share.
