It's honestly some of the most slapdash, lazy shit I've ever seen come out of CBU3. I know we'll never get any straight answers, but I honestly wonder what went into changes that are this half-assed - was it time constraints and they had to push out what they could? Was it lack of testing? Was it the people spearheading the process just, to be blunt, suck at their jobs? I mean, "lazy" might be off-base but... fuck, man, I'm running out of excuses to cover them with. This isn't the first example of this kind of threadbare design in Endwalker, this has been a fucking *pattern.*
At a surface level, the changes seem okay, but the very moment you start putting this into an example/sim rotation or gameplay examples, you realize that this marginally improved a few things that weren't really an issue before (PLD's DPS was acceptable, if not good) while leaving untouched things that are core design/gameflow issues like you've mentioned - spells being on SpS instead of SkS, too many GCDs per cycle leading to us having to drop one, etc. I'd also add in the frankly impressive amount of incompetence that's involved in addressing the "can't block bleeds" issue in Sheltron and *simultaneously* reintroduce that issue with Bulwark, instead of just copying Camouflage and giving it 10% DR and mathing out what amount of bonus block chance it should give to provide the intended ~15% DR over its duration.
Divine Veil is also clearly being punished for Passage still existing (or, rather, Shake It Off was boosted since WAR doesn't have Passage), yet Passage wasn't changed in any way that would make it more practically useful for a typical DF/PF group.
I can't speak for JP, but I've seen *plenty* of fantastic outlines for a rework of the class here and elsewhere. Like... if your in-house people suck, just fucking copy the homework your dedicated players are doing for you and then tweak it here and there to fit what the game requires it to be. I'd be amazed if NA/EU is the only place that's produced high quality "class rework" concepts, though.
