Clan Points Going Down?

How are Clans ranked?

Clans are ranked by clan points, which are received by clan members who are playing online. For every 500 EXP earned by a clan member one (1) clan point is awarded to that player’s clan. Clan points can also be earned by playing and winning clan matches and through special events and promotions to be announced. At the end of each week, 5% of all clan points will be taken/removed. Clans will then be ranked according their number of remaining clan points.
