I think the WWE needs to find a way to make up lost revune or cycle out talent from house shows.
Guys like CM Punk, Kurt Angle, and even Benoit might still be in the WWE if the work schedule wasn't that Crazy. Nash left the WWE not because of the money but because he got sick of working 4-5 matches every week plus travel. It's why Brock left the WWE to pursue football. The house show schedule tears people up.
They'd be fine if they didn't have two touring rosters. Their house show revenue can't be that much. They could easily alternate rosters every week too.
