#8 Failing to promote the Cruiserweight division
Cruiserweight matches in WCW were the most dynamic and exciting contests of the show. Whereas the upper card and main event were mostly older, established stars with deteriorated physical health, the cruiserweights were young, athletic, and hungry for success.
All of these elements made the cruiserweight division popular with the fans. However, as the nWo angle wore on and on, the division was seen less and less. Given the style in NXT and ROH is almost a carbon copy of the WCW cruiserweight division of yesteryear, we'd say that WCW missed out on a great opportunity.
