If I had to say what my take is, the Square devs are probably assuming the casual healers want the classes to be very easy. It may be a fear that too much responsibility was placed on them when you compare the olden times to the tank and healer blame in Warcraft. As a result, we got this over-correction pendulum swing. Another way to say it is the devs are implementing the exact opposite of what we are asking for by assumption that a minority is requesting it and the majority want the opposite.

We may have to find ways to poke holes into those lines of assumptions. Not all the casuals want the role to be so easy to the point of being unnecessary and do agree with the suggestions here. The problem is mostly how we reach out to the casuals who are silent about this. Most of them probably don't know or care this site exists, so we and Square can only guess what they are thinking unless they are actually in party with our characters.
