The goal in a bid is to get something you want. It´s not by any means connected to a fair value return or such. It´s definately not "by definition" to get the best you can under limitations.
Generally, there is a feeling from the suggestion's forums here that the current state of mind is "don't touch no matter what".
1) respect minimum allowed bid - I think it's min. (2% of actual bid, $1,000)
2) how about the situation when 2 or more teams set auto bid?eg. Team A bid $100,000 and set max. bid for auto-bid $300,000.Team B set max. bid for auto-bid $300,000.
Well maybe you can stick around a little more before wanting to change everything to ease your management. BB is a marathon, not a sprint. This suggestion has been discussed many times and very good reasons against it has been raised. You can search for those threads if you want.The best reason is "you are willing a certain sum for this player, pay it".
It's okay to suggest things. But before that you should thoroughly search for the same topics in the suggestion forum. It's not really interesting to constantly go over the same points about - autobids, player trades, set minutes per game, money for scrimmages, player loans etc, the list is long. No points in creating the same threads weekly or monthly. If you have read the other suggestions and have a new approach then be my guest, but this is still yanking the same tree.
This game should not have too many automatisation options. If injuries happen set this lineup, if trainee get's injured switch training automatically. Eventually this suggestion comes down to the "what are you willing to pay" to get this player. I have bought players with setting the alarm clock at 4 am. I have bought players bidding the amount I was willing to pay, knowing I was not going to be near comp at the end time of the auction. Sometimes bidding high early will eventually get you the player cheaper as it will lessen the intrest of that particular player. In the end it's better to bid against 1-2 users than 17 as bid wars tend to raise the players price significantly.
