What about scouting becoming real scouting? I mean, ban the unlimited adds to the NT so the scouts will be forced to aks the owner about his player skills, building trust and confidence is a real human trait.
But then how do you elect a player? I mean, you need them to be on the NT roster, so you need a "button" to take them to your team, and you also need another button to fire them from NT, so scouting will continue to exist...
I think the best method to be able to decide if you want your players to be elected for NT is to have an option on your players page to mark/unmark their eligibility.
