I still think Roman should have faced Solo at WrestleMania. That's where the story was heading, but they ended it early and it left both of them with no direction after that. Solo didn't even compete at Mania when he was essentially a main event guy for almost a year.
They still could have done the storylines they're doing now, but saved them for later this year. Roman becomes the Tribal Chief again, starts feuding with Punk and distances himself from Paul because he doesn't trust him anymore. Solo loses his confidence, Jacob steps up in his place, and the two struggle over control of the Bloodline because in Jacob's eyes, Solo isn't worth respecting anymore.
