This tactic is awful. I am playing with BVB and in 5 matches, I've got 4 losses and 1 draw. One of the losses is in my home against Wolfsburg, 0-5. I didn't like it mate, I'm sorry.
Im sad to know that, but ive warned about everything in the OP, the formation is high risky and very different as you can see so against some tactics or teams it can be disastrous if you dont change something, when you saw in your game that you were losing control u should have done something to change it, individual marking, repositioning, mentality, you must try to undestand how your team plays so you can change things.
As i said there are a lot of things that need to be managed to achieve success and i never promised that you will win every game and every throphies !
