I always thought about some drastic change in field service, but now I think it will never change (stop) because is a Sisyphus task.
I don't think they will change anything about the blood. The doctrine already is a mess and almost every JW knows it's already a kind of conscience.
I think they must change the 144K doctrine, there's no way to go on with that. They will never speak again about the trumpets and conventions, that's so embarassing. The entire revelation book is a hot potato.
I think they are heading to a more cultish form than a mainstream one. And the reason beyond that is the GB 2.0 wants to be cult rock stars. And will be worse when they completly leave Brooklin.
