You are welcome…
Here's a some more on that matter...
Just think there are many premade "default" tactics in the game which everyone can use but no one ever think that these tactics is the best you can have and probably no one use them at least without tweaks... so why then you think that "tips" which build into the game about attributes for different roles gives you the best judgment about the efficiency of the player? All these "tips" aren't any better than premade "default" tactics which built into the game.
As I said there's only one way to find out which attributes are "truly" important you need to watch 3D matches and see which attributes players use in different situations and what level of these attributes they need in order to do good.
For example, you see that your Inside Forward who has Dribbling, Agility, Flair, Acceleration = 11 and when he tries dribble someone then in 90% of cases he fails and gets tackled.
Then you try different Inside Forward who has Dribbling, Agility, Flair, Acceleration = 17 and you see that in 90% of cases when he tries dribble someone he successes and runs past opponent.
All these observation give you knowledge about if you want that your Inside Forward were successful in dribbling then he should have Dribbling, Agility, Flair, Acceleration about 17.
Other example, let's say you see that your Full Back who has only "10" for Work Rate atribute in 90% of cases stands off opponents and lets them pass through and your other Full Back who has 17 Work Rate always engage opponents and don’t let them pass though so all these observation give you information about you want that your Full Back contributes greatly to defense then he should have Work Rate about 17.
