Ideas
The attacking wingback role only goes on the attack if said attack is on his half of the field and are not positioning on the field as they should. For example, If you have the ball with your RW close to the box, your LB will stay back very close to CBs and stay there. The LB will only attack if you have the ball close to the opposing defense on the LEFT half of the field and will only make runs ahead, same for RB on his side. They wont position on the attack when you have the ball like it's shown in the tactics "with ball" formation but instead only make runs from behind if you have the ball on his side and close to the opponents box. I've yet to look into other positions roles but I'm sure others are bugged too because tactics feel way off from last year.
Yeah I've noticed the same as well with 5 at the back. I had both wing backs set to attacking wingbacks (attack) and they barely made a run forward. And during build-ups they stay back even behind the CB’s and don’t support just stand there and when you need to overlap they just stand behind the winger and not do anything and that’s the point of a back 5 system. Please EA fix this. Thank you very much.
