Who said this and can it apply to healers?

this is a problem not with healers but also tanks. And the problem doesnt come from class design but how the game deals damage.
The damage in this game, lets say compare to other mmos with similar high level content like wow, is utterly predictable all the time, is low and is rare. The reason why tanks and healers endgame is about to optimize dps is because it doesnt require much brain power to optimize mitigation and healing, cause there is barely any.
You can remove all of scholar dmg skills except one and that skill would be still the most pressed, cause there is not enough incomming damage. Thats not a job design issue
Edit: Well having boring dps rotation on healers i a job design issue i guess, because the core of the game is still the same (and i dont belive this ever gonna change).
