#5. The Proto-Women's Revolution

Despite portraying a somewhat off-kilter heel, AJ Lee spoke of the need for WWE's women to break out of their shell long before anyone would have you believe this revolution is Stephanie McMahon's brainchild. This caused a schism in the way AJ Lee's portrayal clashed with her popularity, much like Becky Lynch today (Classic WWE booking).
As such the management needed her to face someone whom she might not completely overshadow, so on the night after Wrestlemania, comes in the young fiery Paige. An antithesis of the WWE diva and everything that AJ had been espousing. The young woman had stirred a growing interest in the women's division on NXT and beat Lee on her first night for the Divas championship.
A change was in order, but it was all for nought. Deciding as they often do to the point of ruination, Paige got stuck with the gimmick of a fluke rookie that stole any thunder she brought with her from developmental.
Four months later the viewers grew bored and an AJ Lee return saw the two women duke it out and subtly turn from their alignments, to crown the nerd goddess champion once again. This was the revolution before the evolution.
