[Autumn]

This does not rise up from nowhere, it has been a largely in-part development over time. With more classes getting easy access to crit evade and improvements to their own kits that have lined them up with stats that go well with Crit Evade, like BKs finding LUC to be an overwhelmingly desirable stat, or Bonders getting access to some incredible basic attacking tools. But that's not the only reason either, the nerfs in question so far may include:

-Keyshot changed from 30 Critical rate to 15
-Zerker Shell quartered from what it was
-Old Fitting Form removed from the game (Ghost honestly hasn't recovered from this)
-Northern Wind changed from 32 to 24 crit.
-GR2's entire existence making Poise a worthless mechanic

And a couple more side-points that do effect the general worthwhileness of critical rates:
-LUC's changes in GR2 that make it significantly less desirable as a stat for the purposes of offense.
-General player knowledge floor has raised drastically (this is a good thing)

Regarding poise, I have attempted before to address how completely useless it is to a duelist and how crucial it is to their gameplan to have critical rates, and I was met with the usual disapproval over buffing anything basic attack related (especially when related to duelist). I have since deleted the thread due to my opinions from then lining up a bit differently now, but I have attempted addressing this from an individual case.

As for if this is a sudden targeted nerf? People have been pining about the Crit vs Crit Evade dynamic for a few months now in the main discord channels and sometimes on the OOC, it is a problem that is rooted somewhere that I don't think anything but a numbers change somewhere can change that necessarily.

I find it a little odd that crit evade is advantaged on a stat level due to crit evade being used as a baseline for it to be determined against, but that changes significantly with items and skills, I can't deny that.

Crit Evade would be far better as a crit reduction stat than the outright denial of crits which are essential to some classes to even function correctly. That is the only rework I could see to the stat being present, but as it stands I think Boneheart being +25 crit evade is far too effective on an enchant when most enchants are valued at 5-10 on any individual stat's level.

Its worth 25 of a stat, 25. Most are worth 10 at best.
