I like that idea as well. I've even mentioned an idea where raid gear could be dismantled to grant an "[i]Infusion of Light[/i]", which can be used on fully upgraded legendary gear, granting it +3 light, allowing it to go from +27 to +30. This way no new gear need be made, nor NPC token vendor to trade that gear for that currency, and allows for players to run the raid to max out multiple gear sets already present in the game. It also serves as a final step in gear progression just as raid gear is designed already.
