This kind of thing drives me nuts. I have had without training walls maintained a 5 star in this. The game arbitrarily with no actual cause plummets it to 1/2 a star. It then takes weeks before it just arbitrarily goes back to 5 stars despite my efforts to bring it back up. I also am one who refused to spend tons of time hiding a bunch of training walls to fix something that should not be happening. Why they don't listen to us and take some of the buildings and items in the game that are of a righteousness category and make the that category I will never know. I've posted lists a number of time if I recall correctly as this topic has come up in the past.
