Move servers to one that doesn't run off GS
I recently moved two toons to saurfang to help friends out with a small raiding guild and that server horde side lives and breaths GS and honestly they have more fail pugs than I have ever seen. I have also seen some of the worst gearing choices you could imagine on that server because most are selecting pieces purely on GS. I took real offense to one VOA group who booted a tank who was nicely turned out 39K HP correctly gemmed and chanted but only had a GS of 4.7K apparently you have to have 5K for VOA on saurfang. I left in protest as I don't want to run with retards who obviously know nothing about tanking yet are happy to kick someone based on what some flawed addon says.
