Lesnar theory

Scott,

    I know you're sick of Lesnar/Reigns questions; but isn't this "Lesnar walks out on the WWE right before WrestleMania" story a little too hard to believe.  I mean this literally sounds like a copycat angle from over a decade ago.  Could it all be a work to pump up Reigns as a sympathetic face conquering this arrogant jerk who wants to walk out on the company?  The WrestleMania crowds are usually mark-ish and there's no way Lesnar get booed unless its a Goldberg scenario where the crowd knows he's leaving.  Better yet, what does Vince do when the crowd KNOWS Brock is leaving, and they STILL cheer him and boo Reigns?
 
 

​I'm amused how people now even preface questions with "I know you're sick of this question…" and then ask it anyway.  
If it was a work, what possible motivation would Dana White have for going along with it?  And why would they suddenly have an idea for getting Reigns over as a babyface now after months of failing to do so?  And why make your big hail mary attempt at getting him over an angle where literally only 1% or less of the audience is even going to understand?  ​
