ALL ClasD members have to get at least 10 advance battles per 28 days or they will loose ranks and could also be removed from ClasD if low rank and no battles. 1 day playing 2 advances will get you the 10 battles that are needed.
If you have family or any other reason you cannot get the battles, please post in attendance room what is the reason.
If you cannot play as much as needed, you might want to move to ClasE which does not have any requirements
