I'm not sure of how works the feature that allow some oldies to extend the contract +1 year once they supposingly retire, I guess but, that the game select players that played for us X amount of games... so, I think can be so nice and interesting, to give these players a bonus of 40% before they retire.
Too I want to mention that as many times we've discussed there would be nice increase the age that players can reach till 40, even if it means pay tokens for renew contracts.
Too has been mentioned the idea to allow some players of +30 age to have x2 Special Abilities, so I think that there's margin to improve the game.
