Correction: it was only horrible after the players realized how useful it is. When the players started abusing them, SE found that players cleared content easier than anticipated, which in turn gave them a reason to design harder events, which then relied on such strategies.
How do you know what is "working as intended"? So you're saying there's no useful jobs or abilities out right now?
So your saying Victory Smite and Ukko's Fury are no longer useful? The nerfs didn't hit them hard at all.
How exactly did they nerf BLM? You seem to just list every nerf they've ever done, regardless of whether it was deserved or not. Or do you think all of those were undeserved? Do you think it's a good thing that MNK get to spam WS after WS with no cooldown at all?
I feel like you take the anti-nerf approach too literal and in the process lose sight of what's important. Saying all nerfs are always bad is a generalization and very short-sighted. It's important to create some balance, and if that requires nerfs, they are supposed to happen. This one is an appropriate nerf and it would have been a good move by SE. Only they should have nerfed their content as well, but they aren't, which is a bad move by SE. Now we're worse off than before, but don't blame the nerf, blame the content, because that is the mistake right now, not the abilities.
With Embrava and PD being overpowered the content works in a way, but it's not a fun way (if you've ever been SCH or SMN to those, you'll understand). I'd rather they adjusted the content to not require those abilities in the first place. Only it would have been nice if they did that before the nerf (or simultaneously), not a few months later when they slowly realize that people aren't doing their events anymore.
