A - Reduces amount of people that can participate in bidding wars as timeframe to bid is reduced from 24 to 18 hours. It also takes away the reward from people who are willing to dedicate themselves in order to improve their squad. Result: Fewer clubs get an opportunity to even bid. Those who manage to do so have any possibility of an edge taken away, so players will be evenly distributed over time. Good for clubs already at the top, even harder for smaller ones to gain any sort of advantage.
Disagree with this. If you're a small club that can't be online at value change then you're fecked as you won't ever have the chance of bidding for the diamonds that appear in the game. There have been far, far too many cases of people missing out on players because the value changes. At least it gives you an 18 hour window to bid rather than a 1/2 hour window.
It's a broken mechanic, utterly flawed and I hate it. Why the Devs thought it was a good idea I have no idea. It's an abysmal feature.
