#4. Trying to soften up Roman Reigns and making the same past mistakes
We doubt this will happen with Roman Reigns, but it wouldn't be surprising if they did. A situation where WWE wants to establish a top heel into a top star is a tricky one, and they will be walking a fine line with how they execute it.
WWE's biggest problem with Roman Reigns from 2015 to 2018 wasn't just their refusal to turn him heel, but also their overall handling of his character and blatant attempt to turn him into the next coming of John Cena.
WWE has to be careful with how they handle Roman Reigns' face turn. Batista's incredible face turn in 2005 was a result of subtle change week by week. It was The Animal whose previous ruthlessness began to change as he saw Triple H turn from bad to worse.
Facial expressions of disapproval, subtle digs, manipulation, and more all led to one of the most incredible face turns of the modern era, and that's a better approach to take for WWE, rather than making the same mistakes they made with Roman Reigns before.
