You're being a bit overdramatic. She sure as hell is not as good of a performer as she was back in her prime, but she's still turning out amazing performances in Vegas since she started her show there a few years ago. She also proved she's still a household performer with her BBMAs performance 2016, VMAs 2016, as well as several festival performances. Also there is nothing about Katy Perrys or Madonnas performances during Super Bowl Halftime Show that Britney couldn't do. Performance wise she's still above many others and with the right production and choreography she could slay it!
