I've noticed that players with preferred role as adv. playmakers generally got a low (about 3-6) creativity attribute and that seems a bit odd as creativity must be the most important attribute for a playmaker, right? We all want to be Maradona but it does seem a bit strange that a PL player with a creativity of 5 wants to play as a adv. playmaker?
I haven't done any comprehensive research on the matter just yet but it seems to be quite common, especially after when you've finished a couple of season.
There are some other issues preferred role/recommended roll thing.
For an example:
Does Xavi prefer to play as a box to box mid?
Zlatan as a advance forward? He´s a 100% complete forward.
Wesley Sneijder should prefer playing as a adv. forward and not as a central mid.
Llorente as a deep lying forward?
There are a lot of examples and these issues seems to get even bigger as the seasons roll past and the attributes of the players change due to training.
