Although I’m relatively content with the transmutation system, there is the downside of it destroying items and making the leftovers soulbound. This is good for the game’s economy, but irritating for players.
What if we simply had multiple slots for each equipment piece – one for the look, and another for the stats? (If you only slot one, it takes both functions.) Gear wouldn’t need to be altered or destroyed.
You would start with one set of skin slots and one set of gear slots, but could acquire more through the gemstore, then swap between them while out of combat.
UI would take some work. I visualize the layers being stacked to display just the top, and sliding out to temporarily reveal all on hover, (stays open if clicked).
This whole scheme would unfortunately skew supply and demand on the market, and creative measures would be needed to balance that out.
I should be writing.
