I don't know if there are any plans in the near future to make traits, particularly armor traits, more appealing, but it seems like it's a move in the right direction. I'd say the majority of people gravitate to infused or divines right now, with some people taking on impenetrable and reinforced.
Just wanted to toss out some ideas.
Exploration - Reduce cost of wayshrines transportation during cooldown with 1 piece or flat out remove all costs to fast traveling with at least 2 pieces.
Sturdy - Reduce fall damage by 33.3% per piece equipped. Three pieces removes fall damage entirely.
Well-fitted - Increase the reduction of stamina cost to sprinting significantly. Increase stealth radius.
Training - Change the name to something like Discipline Increase inspiration to skills on active skill bar as well. Increase detection radius with 2 or more pieces. Increase AP on keep resources and repairs by 100% with 5 or more pieces.
I'm sure weapon traits need some help too, but it seems like the four above aren't used or wanted at all. I'm also sure my suggestions aren't likely the best. But they are a face lift for sure.
