My source is just talking to hundreds of new players over the years and the vast majority of them don’t know about the vast majority of 3rd party tools. Most doesn’t know about any.
And, if you were to ask your veteran buddies that play the game if they would be mad if all 3rd party tools were removed. How do you think they would react? Probably not good. The 3rd party tools are essential to this game.
So I’m just putting these things together and think it’s therefore reasonable to assume that new players will have a much higher chance of staying if all 3rd party tools were easily accessible inside the game from day one.
