i'd like to see more of in Survivor is loved ones visits where the loved ones compete. Most of the times they just kinda sit there and cheer the players on but I always thought it was really cool when the loved ones themselves earned it, like All Stars or Vanuatu.
I'd love for them to do Sumo at Sea (which is one of my favorite challenges in the first place) with loved ones going at it tournament style. Or if there are older loved ones who couldnt really do that there's always the time tested gross food challenge, which needs to be used more nowadays anyway
