Honestly as long as they can perform I see no problem with them continuing. My problem is the casting is all stunt and drama casting, and we are losing a lot of the people I would love a catch up with. I am over Kenny, Evan, and Johnny. Paula and Dunbar and Brad are also getting repetitive. I would love for them to go back to the older casts and entice them into being on the show with a competition and not the drama only. I want anyone who has been on a challenge more than four times to be left off for the new one.
