I spent many days, lots of scenarios with one guy to see how the AI engine works and what factors he takes in consideration before a game to favour team A vs team B. This is far more worse than manipulating or tanking.
That's why I keep saying about this troll AI engine is a mess and developers needs to make it more realistic, not to favor some teams according to certain criterias. If you lie to yourself by saying that this game is "inspired" from real matches and the AI engine works perfectly, then you deserve your fate and I don't bother anymore.
