Old school mutants
players with 400+ white skills ( back then you can find also players with 1000 lol ) are no longer present in this game cause of some Nordeus moves in the past ( 340 limit , no more gk training exploit and no more MOTM in friendlys ) and these where really game changers, they could score from any posistion ( even from midfield ).
Todays mutants players deserve to be called well-trained players and from my experience yes they can make the difference but in some matches their perfonmance can be " nerfed" due to the new engine configuration that make the life harder for the stronger teams against the weaker sides.
