The spy costs you 4 boss coins to complete instantly. It was previously 2 boss coins. The thing you should change is the Doctor. It cost you 50+ coins to finish treating instantly. My player had 2 injuries and it cost me 100+ boss coins to treat instantly!!! Please change that, I have been playing for 4 years and i still have the same problem. Thank you for reading. This is just a suggestion to make the game better.
Don't overprice stuff please!
I don't see how this is a problem, when you use your scout, spy, doctor, lawyer, upgrade Stadium and train players they have a specified duration of time (timers) to complete each action. Using the boss coins to speed up these processes is entirely up to you so if you choose to speed up these features then you have to pay the amount of coins placed on them.
