Firstly, I am damn sick of Triple-Threat matches for the main titles at WM.
The first 19 Wrestlemanias didn't have a TTM for the WWE or World Title. The last 12 have had around 7-8 since (some great, some just an excuse to give someone a Wrestlemania match).
What is wrong is Randy Orton v Bray Wyatt one-on-one? Why are we being teased with every other combination, but that?
Orton and Bray have fought once on PPV, a few months ago. Unlike a lot of matches, this hasn't been done to death.
I also think that this feud doesn't even need the belt. I think the feud should be built on them both playing mind games.
I don't buy Orton as loyal servant of the Wyatt Family. He is too smart and cunning. I think he did it to get in Bray's head, hoodwink him, and like a viper, strike at the right moment.
Bray, too, is a master manipulator. I would have written it that the match a few weeks ago on SD, where Orton fought Harper, and then Bray gave Harper a "Sister Abigail" and chose Orton, would turn out to be an elaborate ruse, where Harper deliberately lost, took the "Sister Abigail", so that Randy would trust Bray, only for Bray and Luke to turn on him. It should be based on who outsmarts who first.
Bray could turn on Orton, and then say that it is a case of "Keep your friends close, but your enemies closer" and "My enemy's enemy is my friend". He and Luke Harper then mock Orton for being outsmarted, and Orton vows revenge at Wrestlemania against Bray Wyatt.
Unless this is a massive mind-game by Orton, I cannot see why he would refuse to fight Bray for the title at WM. Orton has won the belt many times, and it is important to him. I don't see Orton as someone who lets friendship stand in the way of becoming WWE Champion. Unless one screws over the other, this storyline makes no sense.
It should be that both men have been using each other the entire time, and it is a battle of wits and a question of who is going to turn on who first. This is much more intriguing than what we have been offered so far.
PS. BTW, Harper shouldn't be added to make it a Triple-Threat. He isn't ready for a title run, let alone competing for it at a Wrestlemania. Give him a shot at a B PPV first, and build from there, not add him just to give him a match at Wrestlemania.
