The big, exciting district conventions were one of the main things that kept me going through the drudgery of JWdom. I sort of lived for them and they gave me a boost to get through the next year. The smaller gatherings in smaller buildings just didn't have the same effect; they were boring, even sort of depressing at times.
Magnum, I felt exactly the same. I didn't feel encouraged because of the talks. What had a much stronger effect was sitting in the stadium, looking around at the big crowd and thinking that they all have my back. At least once a year I didn't feel like a minority. All of them believed the same as me, so it couldn't be wrong, could it?
I really think that many JWs will go home with a less "encouraged" feeling than the used to have.
By the way, I heard that they will do the same in Switzerland. They will build a convention hall in France and it will not hold space for all of them, so they will split up the conventions there as well. I don't know if it's true though.
