As for Bray vs Lesnar, it was never going to happen on a show like this.
Despite the *****ing that goes on, Bray is protected. They don't mindlessly feed him to people, there's always a point. They know that he's got some monster runs in him, and insane potential. They know what kind of stories they can tell and it's just not time for them right now.
The original plan for Wrestlemania was for Bray vs Lesnar. This was why we had the Rumble spot. He was also meant to do a run-in on the 3-way between Lesnar, Reigns, and Ambrose. He'd take Lesnar out and that would set the match up. But by that point they had changed plans to have Ambrose face Lesnar instead. So the Bray build was cut short. This match was basically just putting a slow log on the fire so that there's more to pick up whenever they start the program up again.
It's easy to start it up whenever so it's not really an issue. Bray wants to get Lesnar, Lesnar wants revenge. It's not like time is an issue really.
