To me, and a number of others in the forum, part of the Itemization issue deals with the quality of items VENDORS carry, as well as the items people can find/craft/trade, after all, itemization doesn't just directly affect the items and upgrades people acquire, but how fast or slow people acquire them.
I suppose with crafting and the Auction House (two things D2 didn't have much of, at least the way they manifest in D3), players have better places to get WAY better items, should they be in the market to buy. So I do understand why vendors carry bare-minimum quality goods...if vendors carried gear that could compete with the Auction House, extremely low vendor prices would easily trump AH prices any day, and there'd be no point to the AH at all as any kind of evolution of trading.
However, has there been any discussion at all on how to improve the experience of visiting vendors, what they sell, how much they sell, or how good the items are that they sell? Bottom line, if vendors aren't carrying viable items for people to buy when they get to endgame, you may as well bring back the Cauldron of Jordan/Nephalem Cube concepts from before launch, so at least if people are only visiting vendors to sell and repair, they can save time selling and salvaging, they can get back out to kill more monsters and see Haedrig to repair when they need to.
