Agree entirely.

This is most visible on plate armor. Prior to the preview feature, I tried dying my first light armor (GLA MRD LNC PLD WAR DRG) yellow, in hopes that I'd get a nice looking golden finish, but it turned out flat mustard instead. I Also tried dying it gray, got a very matte finish with no shine, kinda looks like you're coloring your outfit with matte latex wall paint, rather than getting a proper tinted metal.
