I see what you’re saying however providing a source of pen on a class isn’t a far fetched thing nor is it a extremely powerful buff, however it’s definitely a buff that would benefit the class as a whole from Magicka based and even Stamina based sorcerers. Classes like Dragonknight and Necromancer have access to pen through a ability (Noxious-Boneyard) we also have minor breach on classes like Warden and Templar. Our only outliers are sorcerer and nightblade, but nightblade has a unique pen bonus when attacking from the back end of an enemy(Also has Mark which provides crit for being on your bar and lasts a very long time)Don't forget Major Heroism on streak and Major Mangle on Mage's Fury
