#4 Scott Hall and Kevin Nash
When Scott Hall and Kevin Nash left the WWF for the sunny shores of WCW, things were bleak for the McMahon promotion.
Both men had become staples of the product, and despite the company's efforts to have imitators, everyone saw through the charade.
Scott Hall had been a solid mid-carder as Razor Ramon, so his departure left a hole in the WWF.
Losing Kevin Nash though, was probably worse, as the man called Diesel had been the company's top star, holding the WWF Championship for nearly a year, mere months before he left.
This definitely made WWE look bad, and was a huge coup for Ted Turner's WCW.
Together, the pair aligned with Hulk Hogan at Bash at the Beach 1996, forming the nWo, one of WCW's biggest ever moments.
