I think the defensive approaches are too overpowered. Using aggressive and deep have an almost unmanageable amount of AI assistance compared to when using just high or balanced.
I don't see why everyone can't be forced to play balanced and only change the line height and not how the AI reacts or positions themselves, we have the player roles for that.
Saying that, I also feel as if the counter approach for build up applies a certain impetus on the players that makes it more difficult for the player on defense to react to the speed at which the build up is happening.
I think this tactical system is horrible and shouldn't return for the next installment.
