There is a problem as I stated. Squig Herder heal debuff avoiding the gcleanse while SWs hd is cleansed and WH being cleansed by DoK gcleanse and WE not from WP. There is a clear disparity between the ability to cleanse being just stronger on destro by having Orders main cleanser cleansing less.
Its not even a hard fix changing 3 damage types makes cleansing completely balanced between all healers. That were only the way they are because mythic couldnt make the lore fit with SH and WH not being able to be magic related type and instead being ailment.
These kinds of disparity are overlooked by the population because they are so fixated on their own class. Balance the foundational elements and then you can balance classes side by side. Otherwise any balancing between WH/WE SW/WH WP/DoK is lacking an important factor.
