I had a thought while remodeling our FC house and was wondering why items such as ADS Illuminate, or Primal drops weren't done through something like a Free Company achievements system.

This sort of system would be fairly simple I believe, and based off personal achievments - basically the first time a group defeats raid content (such as Twintania), the FC gets an achievement with a furnishing reward (or similar).

Some furnishings could be something as simple as a banner, or a picture on the wall of the content that was defeated, or something more extravagant such as the Primal or Coil furniture.

This would then mean that the achievement furnishings/crafting items would become untradeable, and it would actually mean something to have these furnishings displayed in your house. They become a trophy, rather then just another thing you can buy off the market.

It could also be another, more subtle way to differentiate those that complete content without the coming "Echo" buff. Such as the difference in furniture from the Hard and Extreme mode primals. (Potentially a couple of extra effects, glows, or lights somewhere on the object).

If an FC did wish to get this particular achievement - all they would have to do is turn the Echo buff off before engaging to receive the higher quality item.
