I have noticed a lot of small texture details on NEW armor sets are surprisingly low-resolution
Take a look at DRK's level 100 artifact chest piece for example. There are small details that are high resolution and clear, such as the feathered broach just below the right pauldron, but then you see the buckles? on the upper left side of the chest that are crusty low-res textures for some weird reason
I'm sure everyone has also noticed Koana's low-res details on his coat too
