That new managers would have to give up their best players (e.g. more senior players) in order to "gain" the minimal advantages that have been discussed. I'm also with GM-Manon. It should be a fun feature and nothing where any advantages could be gained. Something that is very important in the balancing of this game in my opinion. Supporters get a couple of fun features but no advantages. I even think that it's already a small advantage to select the amount of days that a player can be put on the transfer list. I would vote for either everyone being able to do so or none at all ... but that's another discussion.
