The point is, that say that, defensive mentality, attacking one, or hard attack ..one in particular is the best, is a wrong perspective. Theres nothing in this game as "the best".
No formation, no "counter", no particular "orders" etc
The players have a weight inside the team, despite their visual AvQ, this marks the path for some orders or combinations to work or do not work.
I was playing since the begginning with attacking mentality, then I changed to defensive or many times during the live matches to very defensive. Some teams go fluid with hard attack, and thats because in the 1vs1 this mentality makes work the team better and fluid than with the other 4 mentalities for some reason.
The key here, is to have the control of chances/bar possession. It doesn't matter how because there are different scenarios in case one attend or not, and many are chosen with te idea to change the starting orders/formations intentionally.
