Because it takes away personal safety for one vote from a player that discovered and earned that right. The piling of all these advantages with the David's had also just made it seem more brutal. I just have a lot of empathy for someone losing their big shot at survivor in such a harsh way. There is something about the Nulifier brings to the future of Survivor I don't like. Every idol should get to be played as a get out of jail free card and be a moment of protection and calmness for one tribal if played right. No future idol will come with this feeling of protection there will always be that idea of maybe someone has a nulifier. I don't like it personally.
