Pity. I'm set on my high Intellect/medium Perception and Resolve first character, but still trying to decide on class.
Sensuki is right that that are probably not the absolute best tanks but they can still do a damn fine job and can fill some interesting niche rolls. They have the same health mult as chanter's which people use to tank and their deflection can be offset by thier "Divine Terror," "Circle of protection," and "Despondent blows" spells which all reduce enemy accuracy or increase ally deflection.
With 2 of those spells up they actually have higher deflection/accuracy reduction than all other classes
