having autobidding a supporter feature is a big no no as I see it as it really gives an advantage to supporters and that's not the way things should work.
I don't see any wrong in the fact that who ever puts more effort in the game will have better chance of getting better players for lower money.
In case I decide to stay up untill 3:00AM in order to place a bid on a player and make sure I get him then I should enjoy the fruits of my work... It's similar to everything in life, hard work pays off.
Enabling one bid that actually buys the player will ruin the free market.
