#4 Waiting for Sanity
It was recently announced that Sanity would be moving up to Raw and rumors have been running wild that Bray Wyatt may soon be taking control of the group. This shouldn't happen for at least half a year.
Spend time on Raw developing Bray Wyatt in this role. Have him develop a real relationship with Matt Hardy to the point where the audience actually sees them as a team. Daniel Bryan was in the Wyatt Family for a week before he turned and it was not satisfying. Randy Orton, on the other hand, took his time, won the titles, and made a lot of big moves with Wyatt before turning on him and burning his cabin down.
Spend time on Smackdown developing Sanity, make them a force to be reckoned with but still imperfect. There needs to be a reason they need Wyatt to lead them. Give them frustration. The audience already loves Sanity, and they can be a very weird type of Babyface team if handled properly we just need to see the struggle.
This should obviously end in a Final Deletion match with all of Sanity against the Hardy's and Wyatt. This will no doubt end with Wyatt falling back into the Lake of Reincarnation to return to something much darker. I can't wait, but like I said, it can't be rushed.
