I can't stand this God-awful shader system, and I know I'm not alone. It's so frustrating having to stress about my shader stock, or dealing with the expensive glimmer costs to apply them. Miss being able to freely swap around my shaders and armor without having to worry about how many of the shader and how much glimmer I have.
Now I have to stress about those things. I no longer have that simple freedom of looking how I want, when I want. It restricts the aspect of customization for no good reason, and as someone who loves customization, shaders becoming consumables is my biggest complaint with D2.
