Not saying that they would do that just for parses, I was just adding another reason (with other 2 more) about why it would be a bad idea that could frustrate a good amount of people (once again, every healer who doesnt like people to die to avoidable damage woudnt like this) and woudnt really solve the issue, what they mustn't do is design the game around people who dont know how/want to play the role properly because then we end in the situation we are right now. Healers must dps, from high end duties to hall of the novice and all the solo quests, all the healers are told to dps so those who dont want to do it imo shoudnt be listened when it comes to design the job as they lack the proper knowledge/experience on how really the role works, would be like balancing football rules around those who want to play using the hands instead of the feet.
In the way I see it the devs basically caged themselves, if they dont want to touch the dps and want healers to have a proper design then instead of giving random spikes of damage they should change all the GCD heals so they are no longer the heal version of the 2-1-1-1-1 and increase the hps requirements for every kind of content in the game, requiring a lot of work as it should be a retroactive process to not make the content from lv1 to 80 dull and boring and furthering from their goal of having an accesible normal mode. Thats why I think dps/support should be the most reasonable paths devs could follow for healer change (and the one modern mmos tend to follow) as mastery of those shoudnt be critical to do casual stuff (newbie friendly), ideally would reward players that have experience and play properly (higher skill ceiling) and no matter the challenge of the content it would work as its an interaction that doesnt depend on external factors, while healing depends on the upcoming damage.
