Bandwaggoning is a real pain currently and damaging “server health” something really needs to be done to reduce it.
I have a suggestion – add a multiplier to server transfer costs based upon the number of times the account has previously transferred.
This would mean that the cost of bandwaggoning would rise the more you did it without any additional hurt on more legitimate transfer reasons such as those who wish to transfer because they found they joined a different server to a friend and wish to join them etc.
