Guild Wars 2

So my server has been with the same other servers for a month now. I thought the winner for the week was supposed to get bumped up and 3rd place bumped down while 2nd stays in the same tier. Why does it not change every week? If my server is always in 2nd, shouldn’t we have 2 new servers every week? One coming up from below and one coming down?

Rating is the game, Glicko is the system.

Yeah… here try this =P

They are still using the Glicko system from last I heard
