White items really had their place in D2. Runewords combined with superior / etheral affixes really expanded the item hunt.
In D3 we are given the crafting system, which is cool in some ways. I like the idea of breaking down old, useless gear and turning it into something useful.
I have a little trouble understanding the purpose of white items past level 7-8 other than filler. I had an idea that white items could be implemented into the crafting system.
What if you could reduce the gold cost of crafting and retain any base mods (superior or w/e) by using a white item as a reagent in addition to the other materials. So lets say you find an item with +15% damage, you use that to craft a rare weapon and it retains that +15% on top of whatever it rolls. (I just want to clarify that this would be an optional material - you could still craft without it at higher gold costs and perhaps a longer craft time)
I think the crafting system should have a lot more options for customization. You should be able to add gems as an optional material to get a 1-2 fixed item mods (similar to cube crafting in d2 - blood items, safety, hit power, etc.)
Overall I feel that the crafting system has a lot of potential, it just needs to be tweaked. A solid crafting system adds replay value and reduces dependence on the auction house.
