let's put it all in place
1) there is a system of training
2) there is a system of buying and selling players between the levels
on the first point - the training system with a limit of 340 for skill - worked and allowed absolutely all managers to train players from 3 * and until the moment the manager will not stop or will not reach 340 in any skill.
on the second point - the mechanism for buying and selling players between the levels was and is now - no absolute change
what a farm is - the consistent implementation of points 1 and 2.
proceeding from this - point 1 of none of the managers was not violated.
Also, I did not find a single point in the rules that would directly indicate that the repetition of the sequence of points 1 and 2 is illegal (not fair).
now as for the solution of the problem by the developers of Nordeus: on the first point - the developers of Nordeus simply introduced other restrictions on training and now training more than certain steps (for example 60 80 100 120 as a skill) increases the cost of training (the number of green rests that you need to spend to restore the condition). This restriction work for all manager!
What will happen in the end - after a few seasons (approximately from 6 to 10) players (with trained skills) of more than 120-130 will disappear altogether. In fact, taking into account the costs, this means that all teams will be brought to approximately one rating, in parallel - it is almost impossible to buy players at auction, scout hunting will begin, and yes - at last Nordeus's century-old dream will come true - donators will buy tokens and win matches.
On the second point - Nordeus did nothing whatsoever you want, and it can be called a good solution only from the point of view of Nordeus's income. It is unjustified by any other considerations to decide on changing the training scheme. And even more so does not kill this decision of the farm - unless the cost of the player from the farm will increase to 2-5 thousand green rests at each stage of the farm (and it will not be profitable to make the whole team through the farm,but you can be limited to 1-2 players in 5-10 seasons). In fact, we would be happy if just disconnected negotiations - this is a simple and elegant solution. And so, in fact, Nordeus has only to completely remove the training from the game.
