Is a matter of margins, thats all. I too had a 7-1 in cup and then a defeat for 1-0 vs..... a -20%... not sure, Ive to check but "what decides the scenario" can set a X distance and fix the chances, IMO this factor has been set more wide lately and Im absolutely against as Ive said many times, same as the recalibration of high scores, and the elimination of limits between skills.
Im actually against many actions that Nordeus had done, as IMO all these unbalance the game.

And well... you know, all is about understand the game limits and use them in your favour as you can.
