Team quality has no big influence anymore. It's becoming normal, that 20% lower team can win and it's not a surprise...
And what I have noticed is that when you change formation turning live game ( in troll game ) it will only make it more worse...

Now I even don't know how big factor is that you should play 4-1-2-1-2 against 4-4-2 etc...In this season it means nothing...
With every new game, no matter how good your team is and how bad the opponent team is, it's 50/50...

In my league there are many games with weird results...
