So you would be fine with an involved DPS rotation that yielded the same results? Well, alright. I'm not as certain others would feel the same, though. Quite a significant number of people.
As for the idea to spice up cards, while it has merit in adding the sense of complexity to cards the end result I feel will be the same optimised singularity the original cards faced with certain classes/cards favoured and others shunned. Apologies if I've misunderstood your suggestion, theorycrafting and the like isn't exactly my forte.

Relative DPS output with more engaging rotations is already what the old healers had, healers are by nature not DPS, 50-60% of a DPS damage is already significant they don’t need to do more than that otherwise you start basically becoming a weak DPS with a limitless amount of support

I’m fine with the level of damage healers do I’d just rather achieve that with an interesting rotation, not dosis spam
