Nice try but I don't agree with you. In Samoa, Russell helped bring down his tribe by voting out the strongest woman, Marisa, right off the bat then he weakened it further by getting rid of the water. Galu brought down Galu, not RussHole.
In HvsV, the villains were doing fine until RussHole decided that he had enough of BostonRob and decided to take him and Tyson down. At the merge, he was lucky (or production helped) that the Heroes convinced themselves the villains were run by the women or else he would have been voted out easily. I still can't understand why the Heroes didn't believe Sandra.
Na'Onka did do extremely well for her alliance after the switch when she convinced Alina that they weren't enemies. That kept the LaFlors together, enabled them to recruit Holly, vote out Tyrone and gain control of NuEspada.
