First of all, stop saying we are trying to say casual players aren't allowed to clear savage. No one is saying "you aren't allowed to clear savage." The only thing that has been mentioned about what you can and cannot clear is if you dig your heel in the sand and refuse to engage with any new DPS buttons added on principle, something the casual healer would not actually do. That is an extremist angle that has been brought up because of players like you who reject anything that has to do with DPS on healers, and how even with that extremist mindset, not only could you clear virtually everything shy of early savage, but you also probably could still brute force savage that way after a few weeks of gear anyway. What has been said is that you shouldn't effortlessly be able to parse purple or higher because nearly your entire gameplay loop is just 1 button, and the only optimization is using your one or two high damage nukes during buff windows. That's not the requirement of savage. Having a bunch of healers suddenly drop to parsing grey, green, or blue isn't going to stop them from clearing savage if they've already gotten into the rhythm of savage mechanics.
And what's more, my suggestion of having an Auto-battle option would actually give you and others like you a tool that would do most of the work for you without you needing to try. You very likely would be able to clear savage even early on with an auto battle button. Would a skilled manual WHM do better? Probably, but the difference likely wouldn't be the difference between clearing and failing, outside of maybe a handful of rare circumstances where the party dies at 0.1%, but that's also a situation where the entire party is responsible, not just the player.
Anyway, for the SCH suggestion, it ultimately doesn't address the main issue of Broil spam. You will still spam Broil constantly, and that's what many want to see change. That said, there are fine QoL ideas here, like I also think Whispering Dawn should just upgrade into Fey Blessing. I'd like to see the faeries offer different values once more--simple things like more burst healing from Eos and mitigation from Selene, but Fey Blessing feels repetitive currently, and there are also more areas that you could consolidate. The Miasma concept isn't where I'd go, but isn't a bad idea either. There is the small issue Sebazy brought up previously about buff/debuff limits and having multiple DoTs likely isn't something we'll be seeing more of in the future to combat that issue. This is why the scholar discussion that I had in the past about my own ideas toyed with the idea that different attack spells would apply stacks of a single debuff that you could then detonate for one large DoT. But at the end of the day, a change like that could be nice, but not really something that fixes the biggest problem. Like a fresh coat of paint on the fixer-upper that still needs reflooring.
