I’ve been trained by earlier versions of Diablo to consider vendor items basically worthless once you start finding your own gear. But since I’ve noticed that a number of players showing their Inferno gear have blue items, it occurs to me that this might be a mistake. Is it possible for vendors to have items that are a high enough level to generate very high stats (like +160 to primary) that would be worthwhile for a higher level character? Or should I continue to ignore them (except in the rare case where they have a yellow for sale)?
I’ve found that they can be useful, especially when you first transition to a higher difficulty.
