As a pretty dedicated Guild Wars 2 player, anyone citing Guild Wars 2 as a great example of loot design has no idea what they are talking about. And I like that game.

GW2 has an extremely flat curve of profitability at max level.

DO NOT SELL THINGS TO NPCs! Marketplace, marketplace, marketplace! Spend the five minutes to realize what things are really worth! Many components sell for anywhere from 100g to 1,000g!
