6. Roddy Piper
Piper is an icon in the world of wrestling and has cut some of the best promos ever. Along with Hogan he is responsible for making wrestling more mainstream but for some strange reason he was never WWF/WWE World Heavyweight Champion. He would have made an awesome heel champion during the whole Rock n Wrestling Connection era during the 80s but unfortunately Vince McMahon thought otherwise. Ill admit that Piper isnt the greatest wrestler in terms of technical ability and his repertoire was made up of a series of pretty basic moves and maneuvers (no one would ever confuse him with a mat general like Chris Benoit, Jushin Thunder Liger, or the like) but he made up for it in others ways. His over the top person personality and natural charisma were enough alone to make him a successful world champion, and I think that Vince and his crew made a huge mistake but never putting the belt around his waist.
