@gizzmo unfortunately this is not illegal, because it is not mentioned as prohibited in the official rules. Yes, as said in previous comments- it may be better if Nordeus returns the things back to how they were- to not be able to heal players, taken on loan, but this way the cooperation between teams will be cut and part of the "group team" spirit will be lost.
I really hope that the developers will think about something soon enough in order for this kind of behaviour to be stopped. We'll see![]()
