1. More thought out, detailed, and logical eliminations, PLEASE
Even fans have to admit that the eliminations in TDI are not the best, and many do not make that much sense, or it is a bullshit excuse just to get rid of a certain character. A lot of the ELIMINATIONS in the last quarter of the season were really sloppy, and to the fans, it is one of the BIGGEST flaws of the season.
2. The people who do not do anything (floaters) need to be ELIMINATED sooner, and the ones who have a story needs to stop being ELIMINATED to abruptly end their STORYLINES.
Fans think TDI does this the most out of the other seasons, with the ones who don't have storylines lasting longer than they needed and should, while the ones that had storylines that were leading up to something were suddenly eliminated with absolutely no closure.
