Eh, it's not all that broken compared to what you can easily do with a fighter or barbarian if you put your mind to it (+3 to hit and tanking ability over 6 levels?). Also, far better than Anthropomorphic Bat, which has 1RHD and 0LA and thus would be perfectly acceptable by the rules you're using. Or the official ghost class.
Removes the bother of having to optimise, anyway.
