Dear Anet,
My suggestion to balance the our current WvW :
Everyone get a free transfer to the Lowest WvW Ranking server of the week.
Transfer Limit : 3 months after a free transfer.
If the person wish to transfer again after a free transfer within 3 months. He/she has to pay gems for another transfer.
Best Regards,
Goonzu from Server Eredon Terrace.
