Yes, but inevitably bidding war will reduce drastically. It's a simple market rule, more offer less price. But i think that revenues lost with the left of a lot of players after quitting the negotiation market are far more than what they're gaining with current bidding wars.
...let me doubt it cause the bids I joined went to +30T xDDDD
People will bid efficently... too we should think that every server have a limited amount of lists, and that these are available with some conditionants... so.... have the chance to switch between 4-5 different lists maybe can be done and it's a improvement.
