If you look carefully, you will see the purple borders around the light Gauntlets, in the Wiki we call it Light Gauntlets (Epic) to make the different more clear. Reinforced Climbing Gloves
But you are right, if such an Epic-Icon is not highlighted it is really hard to see the different.
@Ignasi so some little brighter purple borders would be great even if the icon is not highlighted. Or rename it to XYZ (Epic) like we did in the Wiki anyway.
