I think that we and all the old players of this game, will be agree in that this market don't works so well.... I tanked 2 seasons in level 10, now I'm tanking this and next season in level 12, and usually I have only "5" players of 5* in the market....
When this situation happen, we go to other teams to try to find players, ( me, at least...) and a tool with a option to select candidates, of other real teams of the server, I think can be a different way. Can be like in real life, when a Football club is looking other club players and try to do an offer. Too will be interesting that Bot teams of high levels can accept offers automatically without be added as friends...
I was reading about this problem time ago and did the suggestion to use Mou team to obtain players, but at now, looking that who have the problem at now is me, I try to suggest different options...
Really I don't like the idea to leave my team, and change it for another of low level, like is intended...
PS:At the end the idea is that you, can put a state of "transferable" to your player, and you can put this player in what we can call "visible market", if you have no offers, and time ends, the player will continue as transferable, and may be found easy to recive offers using the searcher. that's = we will be able to sell a player during 24hours continuously...
