Healers have always had a privileged role in PvP. A healer is not like a DPS or a Tank, a healer is like a super class. Healers used to be coveted in PvP because they were so much more impactful than DPS were. It used to require two DPS using interrupts to topple one healer.
Now, as far as I can tell from all of the QQ, things are different. It seems now that "healer" is just another flavor. Instead of depleting enemy health, you replenish allied health. No longer are healers privileged super classes. It seems like they're finally in line with everybody else. You got so used to being able to keep yourself and others up for very long periods of time, that this change of pace is a huge shock. Now you know what it's like to be a DPS. You have a small window of time to be as effective as possible before you die, and little room for error.
No longer will the team with more healers automatically win, a good day indeed.
