It is true that every artist has to go through that, but if you look at Rihanna it is obvious that Gaga really (kinda) faded. She is still huge, but nowhere near Katy or Riri when it comes to new releases, I am just waiting for her next album... I mean, comparing tours and albums isn't right, Gaga is killing when it comes to tours, but so is Madonna, and see her album sales now. People want to see Lady Gaga while she is still somehow relevant and IT, and she is going to have very successful "touring" career, but I think that a huge amount of people, actually to be exact - all people except for stans, lost interest, and she will hardly get people's attention in future. Album sales are gonna drop so much, singles will under perform and it is sad, and at the same time great that she's only been in business for 4 years and she came to that stage already. Sorry if I offended someone, but this is just my opinion.
