Guild Challenger Rating
Dont ask for it to make sense here. So for what ever reason instead of gaining points for the guild team by games played/ games won/ division games are played in. Anet has this one which means it doesnt work.
So take a break and you lose your leaderboard spot, not because the other teams were better but simply because you played early in the season. You will now have to play multiple times a week not to lose points and maintain your score for the rest of the season.
I believe you start losing points after 3 days.
