With the event of players transfering servers with the sole aim of playing the sabatour for WvW purposes, I propose the following two suggestions:
Players are only able to transfer servers where the destination server’s peak is at medium or lower.
Players are prevented from WvW for 4 days after arriving on a destination server.
The first suggestion enables lower pop servers to gain some population perminately due to players not being able to return to higher populated servers, and the second suggestion enables them to do WvW but not have a bikittenact through out that week, or first week when the two week ones come into play.
I believe the second option would be much hard to impliment and will also meet alot of opposition from people, but this would help not meddle with resaults for WvW.
As always please remain respectful and coherant when replying to this.
