There is NO such thing as "Breaking the ME"
This year will be very difficult to make a tactic that will be consistent like the years before, and that`s because of the AI combined with the poor state of this patch 17.2 (in my opinion the worst .2 patch ever).
There are plenty of bugs that change the setup of a tactic : inability of the defenders to mark properly (full backs are retarded), the amount of wrong pass ( most of back pass to the Gk are going out ), under pressure the players are kicking the ball out instead of passing it to someone else, switching the ball to the other side of the field when there`s no need to do that, the closing down setting for more or less is the same (the player will leave his place on the field to close down even if it is set to less).
There are more but this is not the place to talk about this.
They made the AI to adapt to our tactics faster & that`s why it`s harder.
