It seems to me that buying Farm Cash vs. Coins bought are unreasonable rations.
Example: $4.99 gets 7500 coins or 25FC. but to expand my farm costs either 25 FC or 300,000,000 coins. What is it that I am not seeing?
I can expand my farm for $4.99 if I buy with Farm Cash, but if I bought my expansion with coins it would cost about $200.00 real money.
