If the World title match at Mania was Seth Rollins vs Damien Preist, that would be dope because they could mix the Rollins/Priest feud with the Becky/Rhea World title feud from a storyline perspective. Have them out together cutting promos, fighting together when one attacks the other, maybe even a mixed tag match on Raw, etc.
It would flow a lot better than this Seth/Drew feud.
