Let's look at SCH: it was the most busted class this xpac prefairy nerf, and postfairy nerf, it was still overpowered until right about now where it's falling off a bit. Even for SCH, there are a couple buttons that pretty much go unused at high-level play—chain stratagem and physick. Aura blast is 60s CD, and a button like muse is very scripted on how you should be using it each game. This obviously does not mean that SCH was weak, but rather I think this is poor design, and it was overtuned in the rest of its kit relatively. I have never met a person who has disagreed with improving the quality of what little buttons we have and adding a couple more. It will NOT take away from the importance of team strategy and tactics in the feast, just as having as many buttons in PvE does not take away from the importance of it there and having good players in your group.
I think the developer team is lacking someone with good vision and who knows what an objectively good change is—one that everybody wants. Enliven and muse do nothing for some jobs, yet they are an option to pick. If another additional replaced it for jobs that cannot use it and bolt was given to everybody, we now all have 1 button. It's that easy. It's very awkward being without bolt, yet of course it's worth it in feast for the most part. No wonder melee is a nightmare to play in FL if bolt is a must. You cannot stay in fights very long with just recup or sg alone, and some melee like MNK and DRG are lacking in impactful or reliable survivability, and they do not have even 1 type of CC compared to NIN and SAM. Once again, it does not mean they can't be overtuned in other areas—NIN is pretty eh after all. Even autos were removed from melee.
Also being able to see how much damage players can withstand before a shield breaks on them would be a very welcomed QoL change.
