Notice of Removal of MTS, World Transfers and Name Changes (P.S. Notify sucks)

Same NX passing from hand to hand, leaving 7% in Nexon's hand.
That is the profit they lose.

Also, when people buy NX for the express purpose of buying something in the MTS, those are dollars in Nexon's pocket that would not be there otherwise.

Given we recive the full Cash trade system, they are most likely going to buy and sell stuff like cubes to fund their gear needs, so the loss will only revolve around the tax.
