Just need more people willing to step back form DPS and try tanking/healing. Then again, when they put new awesome DPS jobs, it does make it hard for people to want to do that. I can see why healers and tanks are needed for dungeons, unless they make story quest dungeons not need healers and tanks, I doubt they will take off the restriction. You could find some people to join up with, and try it that way. I'm sure there are some people that would be willing to help.
