Right now we are seeing the last few seasons of players who were developed using the GK trick. Even teams that have tanked since the trick was closed will see their players retire soon. 2 perhaps 3 seasons and all these players will be gone.
Players developed using the MOM friendly trick however, will not leave the game through retirement for anything up to another 10(?) seasons. That is of course if they are in a permanently tanking team.
So by the end of 2019 the system should be free of all players developed using "tricks", "cheats" or "exploits"................apart from upselling.
So, I don't think Nordeus will or should introduce any other limits on our ability to train players. 340% for individual skills is expensive and time consuming to achieve. And not knowing at what point white skills stop gaining through training without gaining greys means that when it comes to trying to develop players we are all in the same situation.
I would however like to see something done about the stupidity that is allowing individual skills register as negatives. Put an end to draw manipulation.
