MK-2 will be just under Battlemaster in stats (a couple of points) and have no set bonus. No cash if you don't want it, I think this is the better way to go. So what if you don't need it, just throw it away, no need to give everyone 320K just for hitting 50. If you don't PvP, it will still be a great set of gear for a fresh 50, for those who have been 50 for a while, you don't need the cash, blah blah blah dailies.
