Well, yes and no. Crazy formations propably arent going to perform well, but with new tacical screen its true you can just play generic 4-4-2 , pick reasonable philosophy and stance, and its sort of going to work.
All the comparision and data about effectivness of different tactics is completely superficial. You'd have to simulate a hundred runs of the same season for proper tactic evaluation. Otherwise whatever results you get are statistically irrelevant, as there are far too many random factors involved.
