Before I put a player to auction list today, I trained the player repeatedly to gain as many as sp as possible so as to slightly increase his market value. Sorry to the buyer. You may buy a player with almost zero condition. But I think I have done reasonably unless this is prohibited in ethic code.
In the past, I sometimes would train players before selling. But I rarely train him to zero condition because I needed to wait too long. But now, I can do this in 1 or 2 minutes.
I expect that many players in auction list will be zero condition soon. We better save some green packs if we want to use new players immediately.
Just a change in game feature may lead to many many unexpected phenomenons.
