#1 Time for Creative to build his character
The biggest problem for Roman Reigns right now is his gimmick. The crowd never had a problem with Reigns as an individual but the reason for their hatred towards him is the character he is portraying.
It doesn't matter to them if Reigns is a 'good' guy or a 'bad' guy or 'the' guy. Just take a look back at Roman Reigns when he was part of The Shield. The fans really loved the whole ‘Big Dog’ persona when WWE portrayed him as the most powerful member of the faction.
That went well with the fans but the current booking isn't doing any good either to the company or to Roman Reigns.
Now that there is a gap of 30 days, the creative team could study the case of Roman Reigns with some extra care and come up with a plan to make him relevant again. The same happened with John Cena and Batista when they were faces but the creative team came up with a change in gimmick so that at least some portion of the WWE universe whole them.
Reigns has most of his WWE career ahead of him and such a reluctance to be accepted by the audience is not a good sign for that.
The creative team should make the best out of this incident and could even turn him heel as he was suspended for something bad. All we want is a rejuvenated Roman Reigns upon his return.
