I've done the tweak. Right player now in WB slot with Wing Back Auto duty. So corners work from both sides Played 3 games, tested it. I dont now how this will work in your tactic, but I always prefered wingbacks when they are lone wide man, because its only up to them to offer width.It would require a lot of testing, but if we can make the tactic better that way by scoring more corner goals, then it will be worth it of course I can start looking into it now!
You have fb on auto, which is attack with overload mentality, maybe WB on support will work, offensively they are about as agressive as fb on attack. But true that it will require testing. So that was just a note from me that exploit works with WB position as well, if your new tactic can be tweaked the we'll get again 30-40 season corner goals
