The second school is just redundant, busy work for all, really.
Doesn't this describe virtually all WT-mandated activities for JWs?
Besides, WT doesn't really do away with any activity. Remember when the Book Study night was eliminated? Did WT tell JWs to enjoy their night off? No. That evening now became "Family Worship Night", and in a very real sense, became much more cumbersome and time-consuming than the book study. In fact, WT made it a point immediately that FWN was to be used for what was essentially just another meeting.
