This is probably one of the biggest factors I missed honestly when making a judgement on anything.. But when I looked more at how crafters were, versus how they are now from my own experience, I can at least relate to many of the problems that people have with combat. It was a game that asked for your attention and rewarded you for it if you gave it that attention. Like the inane amount of time it took to figure out how to utilize WWYW without completely obliterating your CP pool, or how long it took to figure out how to pull off a Byregot's Miracle > Byregot's Brow, or at which point it was best to use Brow over Blessing, or just in general the amount of debate going on to find optimal rotations, and with how varied many of them were because control scaled in such a way that it rewarded you for sinking millions of Gil into melding.
I would honestly say though, it's not really for decent players where this issue exists, I would actually say it exists for casuals too.. I mean, I'm probably average or slightly above average if not for the fact I don't really engage with it, but functionally there's no difference regardless of the class I decide to play, bar the aesthetics of it... Viper and BLM were probably the exceptions to this, where BLM feels like a lot of it was intrinsically tied to the content you were doing, especially to make use of mobility. - I just generally don't get why they are insistent on removing versus reworking or fixing.. It's why I don't really have much faith at all, regardless of whether people say it's a step in the right direction, because that fundamental mindset is going to remain the same.. Don't fix it; remove it, then try and add something else to compensate for it, whether that's the introduction of ultimate to accommodate for making savage accessible, seemingly? Or whether it's putting crafters through the shredder and then releasing expert recipes to try and appease. It's funny here, because I would consider myself part of the core audience for expert recipes, but do I find them fun? No, because there's very few abilities to actually utilize where I can gain control of the recipe.
It definitely wasn't intuitive at all back in HW or SB, (Why aren't you using Bane, bro, it's awesome), as there were always little things that would slip through.. I can understand why people took an issue with certain things, but with anything it's best to try and rework it to find the middle-ground versus removing it outright, and even when they don't remove outright, then it's usually subtly plunging into irrelevancy (e.g., GCs), remember back in HW you actually needed to run dungeons, be it sync or unsync, or had to spend enormous amounts of time farming Gryphonskins because the game actually made things like Arachne Web relevant to both recipes and the market, even well over an expansion later, and even if you didn't want to, because it was effort, then you could still sit there and sell Titanium/Level 54/55 gear.
