This is more simple to explain and understand than what it seems, the tactics/formations that make you lose, make others win titles. This is how the perception thing works, everyone believes it's own reality, and top eleven have millions accounts so, everybody have it's own reason based in what they experience, even if they say that the best tactics selection is X, Y or Z vs whatever.
The team configuration is something very particular of each account really, and there's no posible guide in a tactical sense for that reason. Yeah, Ive played a DC and 4 DMC's (DML-DMCx2-DMR) and with the correct players, Ive won titles. We have managers playing without STs... without wingers.... even using a ST as GK, so..... no, the game don't use a tactical common sense. Believe me when I say that Top Eleven, always has been, a puzzle style game.
