And what would be the fun in that? Everyone is able to follow the guide, easy to find on forum. Making it all natar will just demotivate the newer players who don't dare to take one on yet to get a good cropper.
Because gauls have an unfair advantage. This results in people being forced to go gaul if they want the fast settle OR, some gaul, usually 0 prestige, just straight up getting a cropper and later deleting so someone else can claim it.
Also, new players shouldn't get croppers. They don't know how to use them. New players will most CERTAINLY not do a fast settle.
Still, just once a server without it, lets see how things turn out.
Edit: I am not saying you can't fast settle without going gaul, I am just saying they have an unfair advantage in terms of settler cost and settler training time.
