Only a few days ago, I said to a friend that I'm pretty sure if someone said "I quit PF healing" they reaction from Ren would be "Then the consequences next tier are on YOU!".
My crystal ball works flawlessly. I'm officially a seer.

Keep thinking that it's our duty to do something with our limited free time that we don't enjoy to hopefully, maybe, possibly send the right message - or not and then we just wasted several months doing something we don't enjoy.
I find it hilarious that you're seriously telling us to spend our free time on something we don't enjoy and then try to shift the blame to us for not doing it if SE decided to nerf damage again. It's not like a huge gaming company has the option to find out why healer shortage still exists, eh? Nah, definitely the veteran healers' fault who decided to not waste their free time on something they don't find fun.

It's SE's duty to look for ways to get some insight on the issue, not our duty to do something we don't enjoy so that they may get the message. We're the customers, not the other way around. And customers have every right to stand up and leave, put their money where their mouth is, if they're unhappy with something.
