I like to put on Magic-Find gear and go farm for good items, however I've been feeling a bit disheartened lately because of the hours spent re-running acts with over 200% magic find, and only finding yellows that are not even worth putting on the AH.
I haven't tried Whimsyshire yet though, and have been thinking about farming the items to go there.
Does Whimsyshire provide better loot quality than re-running through the acts? Or better opportunies for loot, such as more champion groups in a smaller area?
