I'll give you a tip Top Eleven - Be a Football Manager, regarding to auctions, if you wanna eliminate some of the complaints from users try updating the system to this:
In the auctions the bids tend to go up to a high number of tokens sometimes 13, or 24, so, I suggest that every time an auction for a player reaches 10 tokens, you award the manager who is selling the player 1 token once the sell is made. Overall, every ten 10 tokens bid, you give 1 to the manager selling, that way there's a new more dynamic/fluid exchange of tokens. Who wouldn't award 1 token for every 10 bid? That gives real credit to the manager for selling such good player.
Again, if I sell a player on an auction that reached 24 tokens, then I would earn 2 tokens because it reached twice every tenth token.
Hope you see my suggestion!
P.s. I've been playing for 3 years🙄 I love the game, I saw it evolve and it can only get better!
