Anet I’d love it if we could had some kind of item we could buy off the gem store that added into a special slot that was for pure cosmetic purposes. Taking a regular sword and giving it some kinda additional cosmetic appearance like a glowing aura, trail when swinging. Chance on hit effects and even on death effects. You could go several ways with this. additions for crafting, Gem store items. Chance loot off dungeons/ bosses.
This game is so heavy on cosmetic appearances that the more ways you create new appearances out of old weapons that already been made the less time you have to worry about rushing the newest weapon sets.
