The fact that you can make change the look of a piece of gear is a great addition. The only problem is for some reason, in your infinite wisdom, you disallowed this option between tiers of rarity. This is annoying because it means even if you really like how a white or blue piece of gear looks, you are going to have to ditch it if you want to play optimally. I would really like you to reverse this decision. People's gear score is prominently displayed, so there's no disguising it, and thus no reason to not allow us to pick whatever look we want.
For the orochi at least, the top tier stuff looks way too busy and I would prefer to use some of the blue models.
