2 things you should keep in mind.
1)Don't depend on the counter formation threads so much. most of them are a few months old. nordeus is changing the game engine constantly.
2) many of these advices are crap. why narrow diamond is so good against 4-4-2? of course you have the advantage of the amc and the 2 strikers against only 2 dc but if the opponent focus playing through the flanks with red arrows to his wingers then you also have a problem. why 4-5-1 v is good against 4-4-2? your aml/amr are blocked from his dr/dl and your lonely striker is between 2 dc. whats the purpose to use dmc against 4-4-2?
dv8r is absolutely right. put your best 11 in if you are much better.
the answer to your question about the game engine is that they havent change it yet. but they are going to as they do every season for the last week. that period are happening crazy results. i guess they must have a button ''random results'' which they press to the maximum in order to give some spice to the game.
