#2 To bring the Shield closer together
At the top of the show, we believed that The Shield was over and done for good, considering their match at Fastlane had been billed as 'one last ride'. But by the end of the night, The Shield was closer than ever, united against a common foe. Each man had his own objectives in the division, but the assault on Reigns brought them closer.
We know that The Shield is scheduled to compete again on RAW before WrestleMania. And therefore, the band needed to be closer than ever to tell their remaining story. If indeed Ambrose's departure is a work and he will sign his contract to return to the company, then this move makes all the more sense.

Roman Reigns not competing on RAW forced Dean Ambrose, whose loyalties have been suspect from the word go, to step up and challenge Drew McIntyre. It brought The Shield together.
