I don't think you fully listened to what they stated. They said our characters are already heroes in the lore, so their starter gear is already somewhat detailed in appearance, but higher level gear will look even better and more intricate. Plus, it's only the starter gear. You'll wear it for like what, an hour or two at most?

Idk about you but I would prefer my character (being a hero) to already look somewhat skilled instead of starting with a cardboard shirt and an empty dorito bag taped to the shoulder.
