Card game

[Rumpelstiltzkin]

Instead of mobs dropping cards have a quest that gives you an item. Once mob is weakened, use item to capture it's essence. This essence can then be "imprinted" on a blank card by a crafting profession (maybe any like dyes).

Blank cards can be made and sold, game cards too.

Those two ideas sounds really lame. I would much rather they just dropped, this game really needs regular nice drops to go after both in dungeons and out in the world.
