I used 352 using some tactics i got of redit. Been using them for a couple of months. I start at 4321 and Tierney goes into LM with come back on defense. works well. As soon as i loose possession he goes to LB and in possession he's a LM. He scores a few and sets up lots. My main issue with it is i am vulnerable if i loose the ball in my own half as Tierney won't have time to get back
Try 532, set the wing-backs as 'stay back while attacking' as a default.
then as soon as the game starts activate the 'attacking fullbacks' option.
This basically creates a 352 with the middle 2 pushing a bit more and the wing backs seem to return to a back 5 a lot quicker.
