There are still people who can move the needle, and show to show there are guys or angles that can make a 10% difference or whatever, but yes, from a wider lens it is the WWE brand that draws now, not an individual. It's more about the story & the build these days. A good story can still uptick business and a big star like Lesnar or The Rock can bring in more business.
Remember when the national companies would stress over title changes, because they would be scared shitless of picking the wrong guy who might not draw on the road? Shit, not even just the world champ, things like the tag team titles mattered too, because those guys would headline the B or C tour.
Now title changes are done on a whim and who is champion matters zero.
