I got two awesome pieces of armor in 20 minutes last night doing Ohn's Stand as part of a quest and both pieces were of the same set, a set that I actually NEEDED.
Here's the deal - the number of purple/yellow items in the game is finite. I think if the drop calculation calls for a purple/yellow drop, it starts looking at items your level and below and drops something. But I think it starts at the low end and works its way up.
In previous playthroughs, I was always getting stuff that was below my level and that is one of the big complaints if you read any of the big websites - you can create stuff at any given level that is better than the loot drops.
I am now getting stuff that is closer to my level and the unique (purple) chausses I got last night are better than ANYTHING I can currently forge because I don't have access to the base materials yet.
In other words, my farming of items has depleted the drop table to the point that the game HAS to drop good stuff.
