We don't need everyone to be satisfied, it's impossible.

What we need is for SE to go somewhere with healer design.
I would be fine with either a "green dps" with a rotation complexity similar to tanks and a few supporting skills to sustain the group, or a full healing job requiring a significant part of our GCD usage to be focused on healing spells.

or something else entirely, I'm not a game designer, just a player who want to feel I contribute to my groups without changing role.
