In a world where the developers actually cared about how healers played, we would definitely have more supportive skills, CC options and even a few more DPS spells again. They need to stop treating us like we're the role for idiots who want an easy clear and instead respect that we're just as intelligent as our tank and DPS party members. Our job is to SUPPORT the party - that's why we heal and DPS.
When Yoshida was talking about how good Holy was because of its stun and how they were looking at adding something similar to SCH and AST, I was actually excited because that's the type of thing that healers need and would benefit newer healers immensely in situations where things go wrong if they had buttons that can handle mobs for a moment so they can recollect. Of course, we didn't get Heavy/Slow/Disease/Malady or anything on our AoEs because why would healers get anything actually beneficial or fun?

Why did healers lose Eye for an Eye, a barrier w/ a chance to make the enemy hit for 10% less and instead get Repose? That seems way more useful in almost every situation than Repose is. Was replacing a supportive tool for a shitty ST Sleep that still has the old 2.5s cast time really necessary? Why did SCH lose Virus and DPS got it as Addle? All we have now are just "heal big, heal bigger, mitigation some, mitigate some more" fire and forget bullshit that leaves every job in this role feeling flavorless and like the exact same job. It's stuff like this why I really laugh at the idea that these healer changes are designed to make it easier for newer players. How? Newer players have no CC anymore, they couldn't even bother to make Repose like Sleep and make it AoE, at least then it might have some usefulness in bad situations a healer needs to control. Outside of pressing heal buttons over and over, you don't have any supportive control over situations as a healer, especially in lower levels when players are trying to learn these jobs.

You know why healing continues to be "stressful" for newer players? Because there's LITERALLY nothing they can do except spam buttons and watch health bars ping pong. They can't apply Shadow Flare to slow down mobs anymore. They can't use Fluid Aura to knockback mobs and bind them anymore. They can't use Celestial Opposition to stun them anymore. You know one of the reasons people love playing WHM in dungeons? Because having the ability to do some freaking CC is incredibly helpful and there's never a situation where Holy is not useful in dungeons. But no, SE really thinks that we just love more healing buttons. SE has created and exacerbated this problem of people who only want to heal and only want to GCD curespam, because for 50+ levels now there's NOTHING they can do other than that. If they ask for advice on what to do in these situations, it's pretty much just "yeah spam heals to sustain your tank" and there's no growth, and bad habits start to set in very quickly on what a healer should be doing.

We're very blessed to have these designers that can clearly make well designed healers and put thought into the role and interactions within their kits, and then for some inexplicable reason they remove it all and then tell us to deal with it and that we're never ever getting old job design back. It's stupid and insulting.
