I have a suggestion to make: make resistance trinkets useful.
Variant A: 5-star trinkets giving at LEAST 3x protection compared to current level. As it stands now its not worth 4k ce unbinding fee, unless you're mindlessly trying to protect vs a single type of damage and have like tons of $$$.
Variant B: lower token trinket unbinding price. They're bound upon receiving, making primal spark and other 2 token-purchased resistance trinkets (especially 5-star ones) ridiculously expensive.
Variant C: special "slots" in armor to "insert" trinkets to amplify (or diversify) armor's protective abilities. Because as it is now, my trinket slots (both of them) are busy 24/7 with sword focus modules. Because getting slightly higher resistance vs 1 kind of damage is simply not worth it.

Resistance trinkets are useless. They're ridiculously priced (100 tokens for something with little use), offer very little protection and take up precious trinket slots. Do they even have a reason to exist?
