I do think that sometime away from TV would be the best thing for both Roman Reigns & Bray Wyatt. Since the start of the year Bray Wyatt has suffered from being the victim of some very bad booking from his feud with Randy Orton to Finn Balor just everything about this year for Bray has been terrible. Roman on the other hand has had a pretty good year feuding with Braun Strowman in one of the top feuds of the year in my opinion.
However, I do think some time off would do both men very well as it would give fans sometime to miss them and also give us sometime away from seeing them every week. I feel like the old saying "How can I miss you if you don't go away" has been used a lot in recent years with top WWE stars, but that is because of overuse and bad booking. Even though it might be just be me trying to make the best of bad situation, but that is best way to look at this situation due to it hurting the company not looking at it in good way.
Basically WWE could build up the returns of Bray and Roman once they are healthy to return as a way to boost ratings and in my opinion they should give Bray a few weeks to build his return. In my book they shouldn't be in a rush to get Bray back & should take the time to build it up, but with Roman he could go back to The Shield.
