This whole no ringers allowed discussion gets brought up every season, and It will never make sense to me. No where in any DWTS rule book does it say that the point of this show is about teaching people with absolutely zero dance experience how to dance, no where-Because that's not what the show is about. DWTS is a reality variety show with a dance competition element with the sole purpose of entertainment, that's it. The producers have always wanted a mix of contestants to bring the most value. They want ringers who will give excellent performances, they want novices with potential, they want absolute trainwrecks all for the same reason, because they each bring their own entertainment value.
The fairness in this competition is that the audience decides who they want to vote for for their own personal reasons, this isn't blackpool. You can vote because of showmance, growth, excellent performance, humor, pity...however you feel like it. 23 seasons of this show, with ringers in every season, highlights that having dance experience doesn't guarantee winning, heck or even doing really well (Cody, Christina Millian, roshon, Elizabeth Berkley, etc). Too many other factors are involved.
