Maybe others have thought this besides us. It's just a rough idea. So go easy on us.

Gear and weapons have a nirncrux (somewhat rare)item. Jewely doesn't have a
crux or Bismuth item. Even if a lesser used trait is removed it could work. Adding flat damage percent of some type to your build after so many heavy nerfs might be welcomed. It'd surely be better than the current harmony or protective values and might make more traits viable. Otherwise, things are just the same old stale meta.
if not crux (maybe for lore reasons or timing) than maybe this new material called
Bismuth. It could be that jewelry trait type which ties into the new expansion. My guild mates pretty much think it's a great idea to add a rarer and better trait to jewelry?
It may really be a good opportunity to tie either the base game OR the solstice chapter in with a new jewelry trait that probably should've been there already. Seriously more than one trait is severely lacking.
Have a good time playing
