If you ask for constant healing in fights, you get pushback from the side that prefers to dps.

The only solution is to reduce the skill floor to the bare minimum of simple healing and raise the skill ceiling to appease both sides, then maybe the dev team will actually listen to our complaints for once as we have an agreement between both sides.
