Hi,
I've got a new idea for the game. It is as follows:
On promotion to next level after every season finishes, all our players loose a star. You can introduce a feature called 'Rating Retention' which will work this way- Say I've a player with a rating of 95% and before the season is about to finish I opt for 'Rating Retention' I pay 12 Tokens and the player's rating remains the same next season, only his age increases. The higher the rating, higher the number of tokens to be spent for rating retention feature.
Hope to see this useful feature pretty soon.
