I'm watching some old replays of the Rumble on the Network. Man they had some awesome rosters. The 90 rumble has Shawn Michaels, Hitman, Andre the Giant, Hulk Hogan, Jake the Snake, Million Dollar Man, Hot Rod, Macho King, Honky Tonk Man, Ultimate Warrior, Mr. Perfect and the American Dream off the top of my head.
I think that the late 80s early 90s might be the best roster the WWF/WWE ever had.
