1. Game Matches - many times matches are scheduled too close to each other
2. Condition Recovery - at the rate of 5% per 3 hours, it's impossible to get the player in top shape especially when matches are sometimes only 15 mins apart.
3. Injury recovery - painfully slow. Condition recovers at the rate of 5% per 3 hours and when there is another match, a player gets injured and could be sidelined for as much as 6 days.
4. Builds - building is too slow. At least have a build queue of 2 at a time if building could take so many days.
