As far as people not healing because of the healer changes, I think the disatisfaction is just a vocal minority. I think that people want to be green dps but that actually a large group of healers who purely heal are satisfied with the changes and just haven't been on forums cause forums are more about complaining than anything else. If all healers have to do is keep people alive and not push dps then that opens the role up more to people who wanted to do harder content without having to help push that dps phase.
