I appreciate the long, well thought-out response. I do have a few comments (and not trying to criticize, just giving my point of view).
Maybe I'm cynical, but I think this is because users in those channels are greedier. Here, people generally see the big picture and are more inclined to appreciate the tactical aspects of the game. On Facebook and Twitter, though, you're more likely to get random users that just want everything for free, and to make the game easier and simpler, rather than to emphasize the tactical nuances of the game. I've played for so long because of those nuances; as more of them go, I am more likely to leave as well.
I get the thinking behind this, but I think this is going to be difficult in practice. Everyone is going to be bidding on the same players, and it's going to be very difficult at the beginning of the year to find cheap players, especially if you don't have time to just sit and wait for several 4-minute periods. "Bailing out" is a nice idea, but when people can jack up the price with impunity, it is going to take lots of active watching just to get one player for a reasonable price. This is exacerbated by the shorter 10-second reset period, as it's harder to watch multiple players at the same time now.
Bearing in mind also that we are now seeing high prices for players at the END OF THE SEASON. I fully expect the problem to be much worse when players are trying to retool their squads. Perhaps this could be fixed by having players bid against players of similar levels (revolutionary, I know).
This all sounds nice, but again, it's difficult to get players now; it'll be worse at the start of the season. The fact that players aren't losing anything by bidding just makes the overall prices go up, which causes players to be more expensive than they ordinarily would. That gives players like me, who have to buy players on the cheap to survive, a much more difficult task.
Look, I get the effort that was put into this, and perhaps we do need to give it more of a chance. I am personally waiting until next season to actually try it out because I don't need to buy anyone yet. However, I think the concerns are very real and very strong here, and if we at least get some indication that the team will consider adding back the old auction system in some form if this system proves to have unsolvable deficiencies, we will be more open to it. I have offered a suggestion of having both a Quick Auction system and an Auction system working alongside each other, perhaps this is a doable compromise.
PS: I notice that you did not address the issues teams have encountered with selling players, or trying to see players' stats. Is that also something you're monitoring and considering adjusting?
