I'm all for this, Reigns is definitely a star and WWE have big plans for him, Shields just holding him back. If the group splinters there's no way that all three will be used well. I dont really care for Ambrose or Reigns but if The Shield ends and all three guys are solo stars there's zero chance all three guys will be pushed, one at absolute most, this is the WWE after all. I doubt they could manage booking Batista, Brock, Taker, WWE Title feuds, Authority angle and 3 members of the Shield now gone solo. An implosion also robs the fans of seeing them get their comeuppance, all heel stables need to be disbanded by faces, to pay for their wrongdoing, booking 101. This way Reigns can break away and Rollins/Ambrose can stay relevant and Mason can become relevant.
Would be hilarious if Mason became crazy over and became the star of Shield 2.0, considering Ambrose and Rollions were largely dubbed future stars and Reigns was just the meathead.
