In my opinion, Nordeus made a big mistake to ignore the problem, because they can't solve it easily now.
If they ban all of them, they used it, it will be a statement, for sure. BUT it doesn't give the victims anything. There are lost titles, lost FAs. *
Ignoring them made many managers to exploiters too, because the expoiter get an free advantage over the most managers. No one wants the disadvantage because of them. Nordeus starts with their "strategy" the "arm race", not the managers.
So, do you think it's okay, to ban the managers, who just wanted to defend themselves? But how to different between who started because of his own advantage and the "defenders"?
Think only one moment about a manager, that spends 5€. This poor guy get rapped by exploiters. And now think about one of those who spend hundreds or thousands of € (like Nordeus says). If you are one of this, what would you do? Blaming Nordeus? After one month of ignoring, I can't blame this guys, who use that exploit too. I don't think, it's the right way to ban the exploiter, because Nordeus did nothing.
1.step had to be, that only L3-manager could join an FA.
But... there's another problem: if they don't ban and just fix it... all the exploiters have an advantage over the next few months.
It's ignored for to long. Only "fair" way is, to fix it and wait the next months, to drop their quality.
Finally what's about draw-exploiter? Will they get banned? If not, why? Beause Nordeus make money with them? Sry, but exploit is exploit, no matter what it does.
(and no, I didn't use this exploit, but I think you can't blame the players, if the developer do nothing or for to long nothing)
* we lost at FA our winning streak of 10. 1st weekend this season, it was only one FA, 2.week we faced two (maybe a third, who didn't know exactly how it works), this weekend, we face three of them. If they will be banned, we don't get the points, we had made. We don't get the places we had made. So it's worthless.
