Guild Wars 2

Could anyone tell me how this system works:

http://mos.millenium.org/eu/matchups/medals

Right there it shows the medals won by a server. But how does a server win a medal?
I’ve seen my server (Gandara) win plenty of times, but never did it get a medal.

Thanks in advance.

The medals represent wins in tier 1.

No. With the introduction of the random roll in match making tier 1 and winning it lost it’s meaning. Millenium changed its medal-counter at that time from winning tier 1 to its current

Gold for each time you finished a week as EU/NA rank 1
Silver for each time you finished a week as EU/NA rank 2
Bronze for each time you finished a week as EU/NA rank 3

And Gandara has no medal, because rank 9 was its best rank so far.
