I hope every player can have more than one special ability.
You can see, Lionel Messi is not only an one-on-one scorer, he is also a both-footed free kick specialist even though he uses his left leg very often. Messi is even an aerial attacker sometimes. Also, Messi can be a striker, shadow striker, winger and a 'false 9'.
Why don't Nordeus consider making fast training players to have more than one special ability.
Also, I hope Nordeus to use 'level up' system for the players, which will rely on accumulating experiences. Experiences can be earned by playing matches, trainings. Once they level up, they will have improved skills, and bonus skill points to let the managers assign, 10 skill points are given for each level up. Managers can use these skill points to add their players' basic abilities, special abilities and extra roles. The players with higher market value will gain more experience. The youngsters who come from young academy will have certain levels up already before, and the prize for signing youngsters should be cheaper, at most 10 tokens for a top youngster.
Will you all think that levelling up and experience gaining will be a better quality-improving system than star-based system?
