You don't need to have a vast move set in order be over, and that's where the split lies. Austin, Dwayne and Cena all got over big without needing a lot of moves. Reigns is not even close to being as over as those guys were at similar points in their WWE careers. So the fact that Reigns is not over as the #1 face is the core issue. His actual in-ring ability isn't as relevant as his booking and his character.
There's a common thread with those three that got them over that Reigns is lacking.
