Who said this and can it apply to healers?

Dead mobs do no damage. The faster they die, the less damage overall they do and the less healing is required.

Oh I'm not against pushes where there's a cycle of moves and the added dps helps push a boss into a new phase before the boss's script goes back to another deadly attack earlier in the cycle. In that case you're absolutely right that pushing into a new phase to avoid a rotation of moves can actually prevent a lot of damage.

You also don't need anything other than a dot and a filler nuke like we have now to perform that function. Exactly what we have now so that's obviously not the goal people who push the healer dps meta are looking for. So this isn't the issue here. It goes beyond that into the realm of people who like to dps and that being at odds with the mild pure healers who can understand a linear conversion of downtime to 1 nuke + 1 dot we have now and the sides of pure healers who don't want to dps and the green dps that want every metric of the role to be based on damage parses.

It's a 4 quadrant problem. So my question now is within the mild 2 quadrants of pure healers who don't mind converting downtime to damage and the mild quadrant of healers who like contributing dps:

What is wrong with the 1 nuke and 1 dot we have right now for this purpose?
