As much as I ideally think every healer SHOULD be more than 2-1-1-1-1-1 spam for downtime, realistically SE would absolutely keep one or two ""simple"" as they are very adverse to having jobs with higher skill floor, whether those are perceived or not. (I don't believe readding a DoT or two or adding another attack or two would do much of anything for the skill floor, but I digress)
As unfortunate as it may or may not be, the fact does exist that there are people who like these healers; the problem is that all types of players aren't being appealed to as they are on other roles, right now it's just one group of people who like their healers "simple" when there really should be "simple" and "slightly less simple".
They've done a very bad job at trying to understand what the various camps of different healers want, and it seems like they've really thrown their hands up and completely given up on trying to understand that at all; they seem to even have completely misunderstood what healers wanted with a "DPS healer" (though I think that was an intentional misunderstanding) and they don't get why so many people complain.

This is kind of how I saw it before SGE's tooltips were out back in ShB; it would really suck if SCH was intentionally kept boring and another job was the one that got to have the fun I'm looking for in the role because I love everything about Scholar, but I was fully ready to hop over to SGE and just let the other healers be what they currently were. If somehow WHM became the more engaging and appealing healer and SCH kept getting worse and worse, I'd probably play WHM. It would suck and I would wish I was playing SCH, but I'd also just be happy that there was something that was engaging beyond what every healer currently is. At this point, this is the only balance I can see us ever achieving in this role, for good or bad. I don't want people who enjoy healers currently or enjoy them casually to kick rocks; I just want a seat at the table as well.
