I also manage multiple accounts, but on a much smaller scale (my highest is Silver). I must admit that while bot rentals may be going away (especially for MAX level cards), I find myself renting more cords (to replace Starters and adding a few level 2 & 3 cards to give me that winning edge). So while the rental income may be going down initially, the clientele will probably be gradually switching as people figure this new system out. It might be time to stock up on level 1-3 cards to rent to all those Bronze and Silver players.
