Conquer Club

Awarded to members that defeated 5 unique opponents by winning on each of X maps. Bronze=20, Silver=40, Gold=60.

So, am I understanding this correctly -- to get the gold for this, you have to defeat a single player on 60 different maps? And that I have to do that with five separate opponents?

No, on 60 different maps you have to defeat at least 5 different opponents per map.
So it doesn't matter who you defeat on other maps.

Ah. That makes much more sense.
