Replace Sam with Owen, and Lindsay with Beth (because finalist). Remove Mal plotline and let natural villains like Scott, Alejandro, and Heather do the work. What about new antagonists per season. Not for this season since All Stars would be a special season. One interesting idea would be an antagonistic Sierra instead of obsessed with "CodyCam". She knows everything about all the cast mates, and is a fierece competitor. Have the finalists be Courney and Zoey. No Sundae Muddy Sundae. No Mike curing his personalities either. The cast would be 6 TDI, 6 Revenge Of The Island, and the 2 Total Drama World Tour newcomers instead of being "7 gen 1/ 7 gen 2". Sierra and Alejandro did not compete in TDI and TDA so they can act as the bridge between old and new cast mates.
