If you are a Cases Ladder player ranked in the Top 50 your first priority is to accept your challenges from Cases Ladder Players BEFORE other "league or ladder" games are played. You cannot tell any Cases Ladder Player that they have to wait until you play other "league or ladder" games. Cases Ladder Games have priority over any other "ladder or league" games. If Cases Ladder games are not your priority you should ask for a rank reduction and make other "ladder or league" games your priority.
