I think the only way Bray works as the world champion is for him to be given a dominant run back by a growing Wyatt Family to make him look invincible and I'm not sure Vince would ever give a heel champion that type of push. People forget that Vince hasn't ever been a guy who wants a heel as his world champion. Only Yokozuna and Triple H could legitimately lay claim to have been given a decent run as a heel champion (Punk maybe, but half his run was as a face).
If you look at the figures from when Hulk Hogan won his first WWF world title in 1984 until Stone Cold Steve Austin won his first won in 1998 than you can see clearly Vince's philosophy. In between those two launches of eras a face held the WWF title for a total of 9 years & 8 months, in comparison a heel held the belt for 2 years & 4 months. In that time the likes of Hogan had long runs (4 years, 1 year and 9 months being his three longest), Macho Man held it for a year, Diesel for another and wrestlers like Bret Hart and Ultimate Warrior also held it for multi-month stretches. On the flip side, only Yokozuna had a long run with the belt, clocking in at 9 months from when he beat Hogan at King of the Ring to losing it to Bret at Wrestlemania. Everyone else, from Flair to Slaughter to Michaels & Hart as heels, only acted as 3-4 month placeholders to pass it to a face.
That is Vince's true philosophy when it comes to world champions. It's his blueprint and hasn't changed since, though the reigns have gotten shorter. Wyatt would need Vince to give him the Yokozuna or Triple H push to really make it work and I don't really see Vince doing that to be honest.
While I truly do see your point and love all the numbers you used to prove your point, you are a little off on the just Triple H and Yokozuna "factoid." Just off the top of my head Orton held the belt from 2007-2008 for I believe about 6 months. Which might not seem like it's that long but that is still half a year. Seth Rollins is already had 5 months and I doubt they're having him lose it to Sting(could be wrong) so he's looking for a reign of at least 6 months, dare I say the plan might be for him to hold it till Mania next year. You also had Brock's reign last year which lasted 7 months. JBL had a reign that lasted 280 days as a heel.
Again, not full year long reigns but they were sizable reigns. Especially when you look at them in comparison to face reigns at the top in that time period, they're about equal. Not in numbers but in terms of the longest reigns are both about the same. For instance
1: JBL lost the belt to Cena who held it the exact same length of time as he did.
2. After Orton dropped the belt to Triple H, HHH held the belt for almost the same length of time(a week longer)
Moving onto the topic at hand, Bray has had PPV world title matches twice in his career already...don't get why nobody has mentioned them yet. Back after his feud with Cena was over last year, Bryan vacated the belt. Bray was in the Money In The Bank match and the Fatal 4 Way match the next month if memory recalls correctly.
Does Bray deserve the belt, no not really. I think this is something people need to understand, I think we get confused on this and that's okay. Bray isn't that good. And you might argue me on this so let's view the facts
1. He had a great match with the Shield at Elimination Chamber...but that match featured Luke Harper, Dean Ambrose and Seth Rollins. 3 guys who are widely known to have good matches.
2. His match with Daniel Bryan the PPV beforehand...again, Daniel Bryan won how many wrestler of the year awards consecutively? People say Flair could wrestle a broom, Daniel Bryan can wrestle an okay guy to a classic
3. His match with Cena was good. No matter what we as a community think, Cena can put on good matches and he does from time to time.
4. Taker was good, but it was only good because it was literally classic Taker. This was like Taker versus anybody else for the streak.
Are you noticing the pattern? He wrestles guys who can carry him. He has gotten insanely lucky with his dance partners for 2 years and sadly none of his matches were truly that good. Not a jab at the guy but he isn't some great ring general like a lot of people seem to think.
His promo skills, they're not that good. A good promo guy can go back and forth with another guy, trading insults, building the other guy while building yourself. Or just plain destroying another guy. I want you to seriously sit back and tell me 3 good Bray Wyatt promos. Let me try: you had his feud with Cena(a really good promo guy) when he had the kid sing "He's got the whole world in his hands," you have...uhhh. You got nothing.
But his feuds are classic you bark back at me. But they really aren't. We never really understand why he targets a guy, and the bottom line is, the WWE likes it that way so they can bounce him from good wrestler to good wrestler. Why did he feud with Daniel Bryan? Or Cena(o yea the same reason Kane did back in what 2011?)? How about Jericho? Ambrose almost felt logical. But how about Taker? Or Ryback?
And please don't read this as me hating on Bray Wyatt, the character is a great character and I like the Wyatt family! They stand out very well in a WWE where a lot of guys don't. But he doesn't deserve to be THE guy yet. And he might not ever deserve that credit. It's tough to face that but it might just be the truth. I wish the guy was better, a legit threat to the World Champ but he hasn't been a threat since beating Bryan at Mania. Do I think one day he might win it, it's a possibility.
