I played one levels 1-8, and didn't find it particularly appealing. I never felt like I was powerful enough to keep up with most of my party... At early levels its fine, but it seems to slide down in power, then back up when certain vestiges are available then down, etc. I felt weaker closer to 4, fine at five, and weaker until level 8, when I got to bind two. Of course, the low magic nature of the campaign probably contributed a bit...
