If you are a Case's Ladder Player ranked in the Top 10 your first priority is to accept your challenges from Case's Ladder Players before other "league or ladder" games are played. You cannot tell any Case's Ladder Player that they have to wait until you play other "league or ladder" games. Case's Ladder games have priority over any other "ladder or league" games. If Case's Ladder games are not your priority you should ask for a rank reduction and make other "ladder or league" games your priority.
