3 Reasons the Shield should split up again, and 3 they should not.

Should not split up: Merchandising, Merchandising!

Roman Reigns and Dean Ambrose move a lot of merchandise, especially the former who surpassed John Cena as the top seller in the promotion. But when they are with the Shield they sell even more.

Shield action figures. Shield breakfast cereal. Shield T-shirts, video games, The Shield brand flamethrower....okay, the last one is a bit unlikely but given the amount of merchandise, the New Day has managed to peddle it's a safe bet that the Shield will be providing great returns for some time to come.
