yes exactly. since delegated cards in most cases come from yourself or from friends who have a lot of cards. this proposal is not intended to create any hurdles for legitimate players and investors. but aims to eliminate pests who invest nothing at all, neither time nor money, and permanently extract without any significant risk. or force huge botfarms that own cards to massively reduce their farm, currently they farm e.g. bronze silver chests, with decks that cost around 4 dollars, for comparison a silver cl core deck costs 420 dollars.
or another comparison from a farm i checked, which owns cards for about 2000 dollars but runs 1000 accounts with them. after the change this farm could only run 60 bronze accounts (calculated on the basis of the cp)
