Here's a thought. What if past individucal challenge winners were somehow given an edge over the others during TC? I mean, let's say I won two challenges and went to TC without immunity. Then they'd have to vote me out by 2 votes more than a simple majority? I haven't thought this out but something like this would give more incentive to win and thus standout. There just needs to be some way to also "earn points" during the team challenges.
You should definately send that idea to the producers. I hate when a strong competitor is voted out and the wimps get a free ride. The strongest should be the survivor (in mind and body). I really hope Katie gets the boot this week. I don't like her very much.
