ok first problem its like making a freshmen even more different than they already ae it is good to sort at young age because they will be around people they like because in reality they go to the house they want if they really want to be in that house so whats the point just because dumbledore said does mean its a good idea look what happened to him maybe he should have been slytherine because as we saw he wanted power and was very ambitous (what house was dumbledore in)
