Since nimble is an absolutely worthless perk in the current game version, is there any chance for some buffs? At least I see it like nimble additionally lowers the chance to get a critical hit to 5% independently of enemy weapon bonuses. It gives a nimbler one free perk insted of Steel Brow without which nimblers live till the first headshot/hit. And of course this bonus works only if you dont exceed some fatigue penalty of your armor.
