If this game is anything like RO, and I think in terms of management it will be very similar, they will eventually allow unrestricted server transfers, at a cost. People in RO would transfer from one server to another to make huge profit buy and selling and return to their original server.
This is a huge stream of potentially untapped revenue for them.
I see the current situation of this problem with restrictions being related to the current unstable nature of the game. We are all essentially investors of Tree of Savior…this is a Pay 2 Play Beta Test to prepare for a formal Free 2 Play release, where they will gauge revenue source potential off of our comments and needs in the forum.
