I have received a truckload of requests to sell my account for as high as €10k. Although perfectly understandable and although I have seriously considered it I wont do it. First, it would be violating TOS. As one of the very few 100 % legit players on top level it is not worthwhile to me to ruin that reputation. Second, If I were to transfer my game it would be to my son. That however would be my worst parental decision. He has better things to do such as studying. Additionally, it would take about €5k per month to keep the account in top levels.
I will let my account as is, deteriorating in time stat wise.
Yours,
