"Come to the forums to leave feedback!"
"NO NOT THAT KIND!!!"
Anyway, back on topic:
SE has shown that they won't listen to feedback, so we should be hitting them where it hurts the most, right in their precious metrics.
We can assume that the people who care enough about healers to participate in a strike would be the ones who cleared high end content on it. That means the high end scene would be taking a hit. If they see their precious metrics show a dip in healers participating in high end content, then maybe they'll finally start asking what's wrong, and that would get the ball rolling.
