Overall, it's a great system. However, gold doesn't need to be in there for either of these reasons, you don't notice it among all the other loot, and it won't take up a space. Normally, it would just be slightly unusual, except for the existence of the Midas debuff. When farming bosses in Normal mode, I always use it to get an extra boost (don't remember the exact number, but it was fairly large, 40% or so).[2/3]
