Generally, a 'roll of the dice' should not be a major contributor for the outcome of a match. If that is not the case, then for sure it is not appropriate. Quality and tactics should be the major contributors. If ever some randomness should be involved, then it should be a minor contributor.
I think that there is more than just a 'roll of the dice' that affects the outcomes in this game. For sure, there are hidden effects in this game. Only those that have programmed this game know exactly what they have put in there. But, many things can be deduced based on a lot of observations.
By the way, Nordeus does not play with dice. Do you think that they will risk a lot of investment by playing dice? Most of the things that occur in this game have been programmed to happen with the business points of view being considered. Many things are clearly defined. Someone from Nordeus spoke of variables, but I am sure many of those variables are clearly defined to make sure that things happen the way the company wants them to happen so that they can benefit financially. The bad or in fact very bad, is that things have gone beyond what is acceptable in some cases. It can be compared to exploitation.
P.S: I have observed a lot of things in this game. Some have occurred way to much and similarly that they are neither coincidences nor did they occur due to randomness. In other words, they have been programmed to happen when certain things have been satisfied.
