#4 To tease the potential of more members joining
Growing up, I was a huge WCW fan and one of the things most impressive to me was just how many members there were in the nWo. I know that everyone looks back with the benefit of hindsight and claims that there were far too many members, but back then, at least to me, the beauty of the group was not knowing who would join next.
As the Monday Night Messiah, which seems to be a new gimmick for Seth Rollins, I can absolutely see him recruiting more and more heels from the roster to bolster his squadron of evil and conniving individuals. Maybe Bobby Lashley joins the stable once his feud with Rusev is done and he becomes the fighting machine that we've all wanted ever since we first heard that he'd be heading to WWE.
Maybe Andrade is the next man to be recruited into the fold and he finally lets Zelina Vega go, based on the fact that we've seen a few cracks in the dream team in recent weeks.
