Broken means utterly overpowered. Some of my characters use or have used blue items. These were used not because they were all I had, but because they were superior to the rare, unique or set items we had. So if I was able to keep these blue items and get more extra stuff, they could be quite overpowered. OTOH, if it toned down the affixes to those allowed on rare items, the item could become useless. *shrugs*. And I think that, basically, the socket quest already gives the same sort of bonus (one free item enhancement)...

Some of the class-specific items have been useful, but none of them can compare to the unique ;) .
