Bots and GDKPs are largely a problem on free Xfer destinations. The realms’ economies are also localized to the cluster they belong to. You’ll appreciate the stark differences if you simply log-in to any realm that isn’t a part of a free Xfer cluster (PvE West or either of the 2 PvP East clusters).
I 100% agree. The free transfers have been exploited in Classic Era for over a year. I made a thread about this very issue:
