I suppose it depends on the person... I've never been a fan of customization not related to the game functionality. What I mean is, when I find a new piece of armor, I like my character having a new, recognizable look. But if I can tweak how this armor looks, then this unique look loses its, well, uniqueness, and I no longer see this piece of armor as special. That's why I dislike all these transmogs and color customizations in lots of modern games: they make characters look random, regardless of what items they are wearing/wielding.
Regardless, I don't know, I've always cared about functionality in games and not about looks. Heck, I still enjoy playing original Doom games every now and then, with DOS textures and animations.
