In Guild Wars 2 there was this item you got for completing certain quests as you leveled and was also purchasable with "crown-type" currency.
It combined several items into a single bound-item, destroying the others.
THE VISUAL DESIGN/SKIN of Item A
THE STATS of Item B and C
Becomes ITEM D
For example:
Lets say you have the following 3 items.
1) Twice Fanged Serpent Sword
2) Crafted V12 Sword with Legendary Weapon Power enchanment.
3) Looted V12 Daedric Sword
The special item would combine those three, destroying them all, and produce a single bound item:
With a Daedric style, Legendary Weapon Power enchantment, and Twice Fanged Serpent Set stats.
This was available AT LAUNCH with GW2, and it seems line a win-win for everyone. It takes gear and gold out of the game (helping devs) and allows players an option instead of choosing between sets we need and visual designs we want. I think it belongs in the crown store, and sooner rather than later.
