No offence but I feel this is an utterly ridiculous stance to take! The DCU has always been a universe built on legacy! From the Silver Age characters replacing their Golden Age counterparts (Hal/Alan, Barry/Jay, Ray/Al, Barbara/Bette, Ted/Dan...etc) to the modern age where they themselves have been replaced for a certain period of time as well (Kyle/Hal, Wally/Barry, Ryan/Ray, Cass/Steph/Barbara, Jaime/Ted...etc). Legacy is a corner stone of the DC Universe!
Problems only arise when the successor becomes extremely popular (Kyle, Cass, Steph) or in rarer cases more popular than the predecessor (Jaime). That's when stupid fan wars start and certain fans start clinging to the silver age incarnations despite them not being the orignals either.
Tell me why is Ryan/Jaime replacing Ray/Ted any different than Ray/Ted replacing Al/Dan in the 60's? Nostalgia is one hell of a drug!
PS: It's only a matter of time until those so called"original minority" characters get legacies of their own! Vixen is already heading in that direction!
