Not that I'm disagreeing as I used hardened whenever possible, but when did Rangers switch to Hardened from Supple? Just curious.
It was a while back when they changed crit math for gear. The value for the crit on gear dropped a lot. Some still use supple now though since Dex doesn't seem to have a big impact on crit anymore.
They changed it so that it's a multiplier of your base critical. So, let's say you have a total of 15 critical chance between your weapon, dexterity and passive skills like Armor Weak Points. Let's also say that you have 20% critical chance bonus from your equipment. Your total critical chance would be 15 x 1.2 = 18 instead of 15. It used to be additive, so that would be 15 + 20 = 35. It also used to be a straight percentage, so that 35 meant that you would score a critical 35% of the time. Now, that 18 is a score that's used in more fuzzy math and usually works out to much less than 18%.
