It would be cool if the old raids dropped the ornaments. Or the recipe to make them. Would be fun to have a reason to do that stuff again.
I think a great idea would be for them to create an item to sell in the marketplace that had a 1 time use to make a container ornament of whatever weapon/shield you put in it. This would effectively make them more money and make a lot of players happy that they can get their favorite graphics. There's always going to be the crowd who complains about not wanting to go do an old raid several times to get the graphic they want, well boo-frickity-hoo. I'll go run Convorteum raids for months to get the weapon ornament I want and I'm sure a large majority feel the same with the weapon graphics they enjoyed the most.
Raid items sell back to the raid vendor. It's basically the same thing as crushing, but more flexible.
And since the weapons are so much better you now have to "crush" 10 weapons to make 1 instead of just 2.
