I feel like a lot of the Warlock armor is just trying too hard. We can't just have a plain helmet or robes that are a good foundation for shaders, we have to have some kind of mess on them, they have to be torn in some way. We can't have a simple monk-like robe (Imagine the revolt Hunters would throw if anybody other than them got to have a hood!). We can't have simple armor plate on top of a robe (there's maybe two sets in the entire game that are just "robes with armor on top" and one of them seems too flimsy, and the other one has weird shader formatting on the armor part) the closest thing to a straight robe is the prodigal robe, and even it's in tatters around the edges. If it's not too thin, it's trying too hard to be cool. There is appeal in simplicity, and that's really hard to find in Warlock armor. I know that that sounds like a good finishing point, but I want to specifically mention the Tangled Web helmet. the base model of that helmet, without the spikes and w/e else on it, is one of my favorites in D1. It's a simple hood that looks fairly well armored and accomplishes the task of being a Warlock mask in lore, narrowing the focus of the wearer with the blinders on it. But the only version we have in D2 is that "Trying too hard" tangled web hood, and I just don't want to wear it.
