In this coming expansion we not only didn't get a new healer, but the healers we already had were ruined. It's such a let-down, I get it. But, no one is forcing us to play these jobs.

The only way to show the developers, who judging by the changes almost certainly don't play healers, how bad these adjustments are is to avoid the healing jobs entirely and play something else.

Let the ques for duty rotations go upwards to 45 mins or longer for tanks and dps; then they'll understand the homogenization they've forced onto the healer roles is boring and unwanted.
