You're not reward for playing the game... you never where and you never will because people is ok with it. This first 2 are acceptable,

1st you need 2 teams do to tier mechanics,

2nd do to LU your players are not usable some weeks...

3rd You win little gp for win the game unless you bought some players with coins and spam the competition they update on monday.

4th and the worst of all, if you're not playing the competition on point 3rd you can build a team that even winning all games will translate in negative GP won.

5th a lose should grant enough gp to pay your contracts (incentive to play the game)... tie and win should allow you to win extra gp to then use it.

... they only care about you spending real money in coins and there is little differences between Myclub and a phone game.
