Hi, I'm Yozan and I'm a warlock. About my class, I think the only thing that needs to be changed is the warlock's defensive power, because all the classes that can reach him will kill him. This is because the class has no way of escaping most classes and let's face it, "Stone Body" isn't a good skill. To change this, I think it's good to rework the skill, put a passive that increases the defense or some defensive parameter of the class.
