This can be done by any free player that lives in an area that has good farming (I understand farming is bad in some places). We can farm something like a max of 35-40 boosters a day. I have a deep bench, so i'm at 40% training bonuses every day and have a team budget of $2.58B, so 40% training bonuses and max win bonus isn't costing me much, plus w/ CL matches I make that money back anyways.
