Encounter Design needs to be overhauled at a fundamental level

[SamRF]

Why bother? Most healers don't even use the DPS skills they have right now.

I wouldn't say "most". At least in my data center, I definitely see more than half the healers dps. It's only fair imo for players who get most competent at the role that they have something more engaging to do when there are no healing needs. Adding more complex dps rotation is an easy way to do this since it increases potential engagement in all combat content in this game (solo content as well) no matter the situation.
