User blog comment:TD23120/Discussion: Which Contestants Should Appear Again And Which Contestants Should Never Appear Again/@comment-24301938-20140923000300

I believe some of the All-Stars should return in a future season to redeem what AS did to them (i.e. Gwen, Courtney, Duncan, etc.), but some of them need a break as well.

Everyone else can return to develop/redeem themselves imo.
