Anti-RMT doesn't stop anything regardless how its done unless its screwing up legitimate players at the same time, the only way you are going to be able to do anything to them is by actively policing them in person with GM's. Block them from one thing and they will just move over to another in full force just as fast.

There's already very little need to even bother capping out a DoL as it is, removing the SP loss isn't going to change anything. The limitations need to gotten rid of, every other class in the game isn't limited to 2 hours play time.
