Every job gets a stealth nerf every time new tiers come out.
Otherwise we'd be hitting at 100% crit rate and DH's everywhere.

Stats have always gone up but SE never tells us ingame that crit is generally not ever going above a 35% rate or so.
If you had 500 crit 4 years ago you're hitting the same as having 2200 crit now.

Same goes with other stats, I just like crit.
