If only you guys were around for the Cleric Stance Dance phase of 14, you'd likely change your tune and understand why we healer mains aren't thirsting to return to those days. requiring us to do DPS is fine asking us to DPS with 8 buttons dedicated to just DPS is ridiculous. I think one of the issues is people don't realize most healing jobs do more than just heal dump, Healing, Shielding, Buffing, and DPS is something the best healer job does. The Shielding and Buffing doesn't have to be done at the last second, it can be done preemptively, DPS can then be done safely for a few seconds before healing, buffing, or shield is done again. DPSing on a healer should require you to be playing 2 roles in one job because no other role is doing that. DPSer aren't struggling or forced to do tank or healer rotations, nor are tanks required to do healing or dps rotations to do their primary role as tanks, the latter is built directly into their role.
Healers have simple dps rotations so that as the content its older they don't have to focus so heavily on damage and spend a little more of their time making sure newer players or not as good players stay alive while attempting said aging content, that would be harder to do if healer had to keep up with a samurai level dps rotation and be expected to keep the party alive. Let them have their soft dps skills, so they don't need to be 4 armed keyboard savants to play one role.
