Is that really what most healers are asking for, a couple extra DPS buttons? Does that mean that Sage is perfect as a healer, since there are, um, 4 DPS buttons instead of 2?

You mean Toxicon, which is a DPS loss or DPS neutral if using the stacks given at the start/fishing in disconnects? Or Pneuma, which is a heal that does the same amount of damage as Dosis? Yeah you've solved it, just make buttons you don't want to press but they do the same thing as your 1 button spam! SGE does not have a different DPS rotation than any of the other healers, and it's arguably the least complex in what it has to do for its DPS optimization.
