Having more reasons to wear a certain armor, such as raid mods on raid armor. We have armor ornaments, which are great, so you can still customize your look. Armor, like the Iron Banner set, gives you prisms. Having more than just a few bonuses on some armor would be awesome. Maybe small gameplay changes to add to your build, it could even be randomized and make you look at what you're dismantling. It could be wearing the whole set an option, or each piece gives a small bonus. I'm not sure what kind of ability or gameplay enhancements, but there is a lot we could do to our armor!
