Very unwelcomed change. I'm not even a hardcore "flipper" bit it was very useful at times to be able to earn coins to purchase LS collections or cards I couldn't obtain. I understand the thought process of trying to limit inflated card prices but this handicaps EVERYONE at being limited at such a low number.
In addition, the team knowing that investing is such a large portion of their game so much so they specifically have discussion around it in live streams with ratings adjustments - to not say ANYTHING about this in any of the streams leading up to release tells me they knew this change would not be liked. Staying silent on it and surprising people after the deluxe game purchase feels very predatory.
SDS has always been THE sports game that didn't follow the trends of the others only caring about the bottom dollar. This change is a strong shift to join that philosophy of Big Money spenders will be the only ones able to collect all cards.
