So then how exactly should Shadow Knights be nerfed, because I doubt nerfing Bold Strike would make that big of an impact on the class as a whole. You also can't just go nerfing it without giving it some sort of buff to even things out. As the Fullmetal Alchemist series said, "Equivalent Exchange."
As for that, I am not an experienced SK player. I don't main him for 8 years consecutively, phasing through multiple stages of the game, through every nerfs and buffs. The people that use them should be the one standing out objectively to discuss this and see what should be nerfed. They know them the best.
