I don’t know that it ever made it onto the forums, but iirc there was a discussion in the discord about having gear that ages, etc. The thought being newer players would have brighter gear, while more experienced players would have a bit more beat-up/scratched/etc gear (or even scale with the gear; when you first get a weapon/armor, it’s bright and shiny, but as you use it it gets chipped/worn). I think the eventual conclusion was that that would limit some of the customization and role-playing on backstories etc. Also, from the character creation video, it seems that scars etc. are going to be customizable options from the beginning so that would kinda go against that idea. I do think that if crafting ever became a thing in-game that the aging gear would work better, but wouldn’t quite work otherwise.
This is another similar idea that I really like. If there were “trophy” cosmetics for various achievements, I think that’d be a really neat addition for people who like completing things like that. Could be little rewards like changing name color/border for hitting level milestones, joining a guild, etc. up to big things like capes or glowing auras for hitting level cap or defeating big boss.
