Unfair policy buying using coins – NBA 2K Mobile Basketball Game Review

I spend so much money on buying coins and I get repeat lower grade players. I have literally spent 1000 dollars on buying coins to buy diamond players and I have probably got one till now! There should be something that this game creators need to do to reward users that spend money! At least provide a pool of only diamond players!
