#3 Braun Strowman's one-dimensionality
Over on RAW, Drew McIntyre has been doing a decent job with the title as he has already had a good feud with Seth Rollins and is set to have a engaging clash with Dolph Ziggler at Extreme Rules.
However, with Braun Strowman, nothing apart from Bray Wyatt seems to have worked. After winning the title, he had a good feud with Wyatt and ended up successfully defending his title.
The problem, however, is what can WWE do with Braun Strowman without having Wyatt in the mix? The Miz and John Morrison feud was clearly not the answer (or teaming up with Otis in a on-off match for that matter) so WWE had to bring Wyatt back in the mix again.
The problem here is that the company can't have someone like Wyatt picking up losses on a regular basis but also cannot have him win because that would make the champion look weak.
Also, if Wyatt eventually wins the title, the options are limited for him as well since there is realistically no one to challenge The Fiend (ahem, Goldberg).
This makes Braun Strowman's run really one-dimensional, especially when compared to Otis, as there doesn't seem to be anything interesting for him apart from feuding with Bray Wyatt, which will also end up being counter-productive in the long-run.
For Otis, this will not be the case (more on that later).
