While I agree that mboxes are op, I don't agree with removing them at all. I will suggest maybe instead making them their own donation rather than being obtained from bonds, making the price of them like $5.99 or more (people will still buy them) so people buy them for more in-game. This way, there wont be AS insane of a profit from getting a good item AND bonds go back to being the price they were prior to mboxes (100m for the people that literally only want to buy them for gold membership is insane).
