You forgot
#00: This point is so important, it's coming even before #1! cRPG is still a beta, and it's still being worked on. Since a beta is not for entertainment purposes, but to work on balancing and fixing bugs, the devs are relying on your feedback. So whenever you got killed by someone and you had the impression he did it with ease, it's probably OP.
Don't hesitate to go to the forums and report your observation. That way OP things can be nerfed, as the devs are working towards getting all the OP stuff in line with the heavily UP 2 handers. So please don't be lazy and help improving the game!
