The concept of this class is interesting, and there are a lot of fun ideas in here. Unfortunately, the concept is also pretty specialized, and would require either a campaign centered around it, or at least a campaign with some very different assumptions from core D&D. On top of that, elements of the class step on the turf of core classes (especially the fighter) and they seem too powerful at times - especially once the subclasses are factored in. All of which adds to the feeling that this class wouldn't work well alongside standard characters. Lastly, the presentation could stand some improvement. Overall, this is a neat idea that needs a lot more work. On the upside, it is PWYW, so at least the price is fair...
