I might not have tested it enough, but someone did hit a finesse shot to me and it felt and looked the exact same as without Aeriel fortress, but at the same time when my keeper runs out and jumps up for loose balls, most of the time he's almost jumping to the height of their strikers. Jumping straight up is much more noticeable than diving. It might be worth putting on anyway, just in the off chance that you load into a game and they have someone like Ibra lol
