Played with this build using the 4 player mod over the weekend and it went great. I think I was the strongest character of the group even without armor or a shield. I often felt like I had double or even triple the action points in combat so it was very easy for me to move into combat, take a wack at an enemy or heal an ally, and then run back out of harms way again.
Everyone else in the party died at least a couple times and I had to come to their rescue (which they appreciated). My character (Kyra) only died once when my son, playing a pyro mage, nuked a trap and blew us both up.
Lots of fun, this build works great. Even without the armor, she still felt a little overpowered. I guess Lone Wolf is just a Mary Sue trait.
