Nordeus does give the option for all managers to 25 free savable greens + 15 non-savable greens to refresh as much as they would need to.
I also understand well you do not take them for your own reasons there, but then it is a tad unfair to suggest Nordeus wants to kill the game (by exhausting managers’ greens to an extent it is killing the game). Definitely costs more to maintain the teams, but still well manageable. It is a bit unrealistic to be able to run the team to perfection in terms of fitness without inputting anything at all (if so, everyone will have saved up tens of thousands of all packs very easily - then everyone will then start complaining why they would have tens of thousands of greens, like money, sitting in their reserves for nothing).
