I rarely ever sell anything on the auction house and I have all the money I need for any of my toons just from questing. I don't understand why anyone should get in trouble for selling anything in-game for whatever price they feel. If I happen to get a bunch of gems ill toss them on the AH cheap to sell them. It shouldn't matter what I choose to sell them for.... this isn't real life and the auction house shouldn't be treated as if it's that important to the game.
