As I write this, I've just finished watching this week's Raw.
We all know Batista is headlining Mania, having won the Rumble. The big assumptions are that Daniel Bryan faces Triple H, Taker gets Lesnar, all of Bray Wyatt's good work gets ruined by facing John Cena, and Orton defends the WWE title against Batista. Aside from Taker / Lesnar, WWE has started booking things for all three other matches, so I can't see too much difference happening.
The problem with all this is simple: it's a bit shit. And the reason it's all a bit shit can be summed up in two words:
Randy Orton.
Going back to the Rumble, Orton was the number 4 guy in WWE. Behind Cena, Punk, Bryan, and then Randy. He's not actually got an opponent at the moment, his run with Bryan has finished. Cena is facing wyatt, once they're through with the Shield. Bryan has Triple H and Kane, lesnar and Taker will be sorting themselves out once they're back on TV. Randy Orton is losing weekly, which is making him look even worse (incidentally, why WWE gave Kofi such a huge win and have done sod all with him since pretty much sums WWE up at the moment).
All it'll take at the moment is three simple switches...:
Turn Batista heel, align him with the Authority.
Orton loses the title to Bryan in the Chamber.
Switch Bryan and Orton over in the above matches.
Mania 29, I only decided to order it the day before the event, when Vince did the big reveal of the stadium. If they go with what I think they're going with, I don't want to see Dave closing the show and winning the title. Ever.
