I was surprised when I read this class. I bought the bundle, and this was the class I was least interested in, but I'm glad I bought it. The class abilities gained have great potential, both as an individual and in a team. He isn't as tough as the Monster Slayer, but his combat abilities could easily be a life saver. Depending on the options you take (such as the class you use as the entry point) and the opponent you face, you could easily be a better combatant than the Monster Slayer. In fact, you could be a quite nice Monster Slayer Slayer.
The three Feats posted in the back are really nice for anyone who uses a fencing weapon, and the stance for the first one would be very frustrating for many opponents (especially combined with "No More Games" class ability). The would then be unable to spend action dice to increase their attack or damage against you, as well as be unable to apply any tricks to actions targeting you (with 'No More Games'), which should make you quite a bit tougher than normal.
