Just troll the PVP guys. You get 2 marks if you lose and 3 marks if you win so why not? If Bungie is going to screw you then screw them back. Fight fire with fire. Go into PvP and do bare minimum until all the hard core PvP players get on here and blow up the forums complaining and maybe Bungie will change it back. If not, well you still get 2 marks for every loss. 15 marks a day will get you the max of 100 in a week.
