I will always prioritize my friends, FC, and Linkshell mates. I reserve my queues for them and them alone. If there just happens to be a spare spot and a random DPS gets it, then good for them. However, I am not going to go out of my way to queue for something that I don't need to do at the moment. I will do my daily roulettes and there may or may not be spots available for randoms to join in, but I won't do any past that unless requested by friends, my FC, or Linkshell mates.

Right now, the problem is that a number of tank changes has made tank players quit their former tanking jobs for DPS classes. It's up to SE to bring those players back.
