There are many possible explanations for bad outcomes. Some might be due to managerial errors including the use of improper tactics, but for sure in some cases there is something else involved. I have seen a lot of 'nonsense' happening in this game. I have also observed trends, and also indications showing how things have been decided that your team won't be favoured.
Don't think that if you spend money buying tokens, you will have more 'success' in this game. You might have well bought a lot tokens and have a worst season than you had. This game has some things programmed in it so that money can be 'extorted' from users. I have bought a lot of tokens last year (2015), and I have observed a lot of bad things. I highly suspect that there are things in this game so that certain users are identified as potential targets.This also explains why some users that did not made any purchase or did not made a purchase since a very long time did not experience certain things.
I already quit this game once in 2015 after having experienced many unacceptable things. Some of things had repeated in this season. I have posted several things concerning this game. You can read and make your own deductions.
After all that I have seen, there is no way I am going to spend more money in this game. It is much better to use this money for something else. I am already considering whether I should quit again. The way this game functions, has hurt a lot of people. Those that lost a lot of tokens in bids in the auction market may have been affected in real life (sadness, depression and so on). The important matches that users should not have lost too, that is where they had superior tactics and quality, have hurt them too.
This game is far from being a proper football management simulation game. It is a game based mostly on business. There are surely a lot of business ploys or strategies in this game. This game can be compared a lot to casino games. There are also some unfair things in this game, for instance a user having significantly more offers than another user. I, for instance, I never had a token or a pack from offers since I started playing this game, while others users can earn as 50-100 packs daily.
The best advice I would give someone concerning this game is to stop playing it. If you can't, due to your weaknesses, for example addiction, at least limit the effort, time and money you spend on this game. While this game might be fun, especially at the beginning, it is also a source of annoyance and worry. In playing this game, you might be penalising yourself and also contributing into other people's sufferings. Also, you will be contributing to something that seems to be bad as whole.
I have contributed a lot to this forum. From now on, I will no longer contribute in any way that it benefits Nordeus. It would be bad to help something bad succeed.
