If you've been following on KMS news, you would know that the 5th Job Update merged Min Crit and Max Crit into the single Crit Damage. The reason why it happened is because if your Min Crit exceeded your Max Crit, they would be swapped, which KMS called it stupid.
I was really hyped for this change! But here's the thing, by merging the two Crit Damage stats into a single stat, they also merged the two bases into the same stat and the new Crit Damage stat has a min base of 20% and a max base of 50%, and having Crit Damage increases both. So what you ask?
On one hand, this is a huge nerf to classes that were able to have their Min Crit stat get close to or exceed their Max Crit stat, because now they will always have a 30% Crit Damage difference.
But on the other hand, classes that had their total Max Crit increase higher than their total Min Crit increase (I'm looking at you Marksman!) will absolutely love the Min Crit and Max Crit Merge, because this will eliminate the problem of having very unstable Crit Damage.
Also, by merging the two Crit Damages into one, their Hyper Stats got merged as well, saving you Hyper Stat Points, therefore allowing you to distribute the saved points elsewhere.
