Renathras. You are missing the point of every whm main current and former who does not want it being left behind as you propose continuously.
If there is any healer that should be easy (IE low skill floor and ceiling and no kit interactivity) its sage as it was designed for EW's super low requirements

The other 3 healers had history and dedicated playstyles with skill ceilings that should be returned and whm was one of them. Sage is currently stealing sch and noct ast's playstyles. It has yet to carve out a niche for itself


that being said- interesting thought experiment and one that i would not be surprised to see happen at this point
