Here is just an exampe @lvl 300, just say Zalciai reduce by 350 and enemy has 50 crtresist, and you have no equipment to add crit (Your own Crit rate = 3)
Before : you will get 3 - (50-350) * 42 / 300 = 42.%
Now : you will get 3 - (50 - 50) * 42 / 300 = 0.42%
Sadly dude, Its that bad :'(
Not even noticable again as party buff
Even with high Crit Rate equipment, you just better go to DEX now
I hope devs will change it again :(
