It's pretty frustrating that Sage is so close to having a good DPS kit and exactly the sort of thing healers need.

Genuinely if stacks of Addersting made Toxikon II do more damage from 360 to like 420 and you gained those Adderstings from shield breaks psych uses and dosis crits SGE would have exactly what we would want.
This is a very simple resource build and spender system that you can easily switch between doing and healing but keeping the job more engaging for when you learn a encounter.

The problem is however if anything close to a system like this was placed on SGE we would never see the other healers ever again in roulettes.
