While there is sure to be a difference between a 'good player' and a 'bad player' in any role, I wouldn't want them ever basing changes to those classes of the latter end of the spectrum. Especially with healers. Mechanically, they're not difficult to operate. Some like AST have a little more juggling to do if they're going to keep their buffs going and heal but none of them require super tight rotations. Most of their difficulty comes from knowing fights, acting fast, and anticipating incoming damage or mistakes.Its less about a sequence of buttons and more about knowing what tools you have in any given situation to right it should things go sideways. It's what I love about being a healer and a WHM: bringing things back from the brink. That is my reward for playing in the same way big numbers or things dying faster serve as a reward for DPS players. If they make it so a poor player can do nearly the same thing as a good one...where is the satisfaction of playing that role any longer? It would be like if they said they were going to make it so a bad dps who fumbled their rotations and a good dps who did their perfectly did essentially the same damage anyway. Why should any player try to be good then if the reward isn't there and you can get the same result by being sub-par?
I think this is why people, myself included, are worried about the comments of making WHM 'easier'. It's mechanically already the most straight forward of the three mostly straight forward healers. I don't want to see it stripped back to nothing just so it can have training wheels attached that make poor players feel more like good players. Are there things that need fixing? For sure. Lillies need to go or be redone, I'd like to see something added that gives me something to do when people aren't messing up and healing requirements are low other than spamming Stone, I'd like better cast animations that feel equal to what they give the other healers, I'd like a niche of our own outside 'pure healer' which doesn't work from a balance perspective, and yes I would like to see some fights that are more challenging from a healing perspective. If anything I want a little more nuance and complexity, not to be made easier.
