It's not like restoring items takes effort... a Certain MMO has the process practically automated for certain cases (vendored and disenchanted items). You get three restores every 30 days there, and I certainly can't think of anyone who abuses it.

This is a game. It's not some place where people should feel the need to get on their mighty high horses and demand that some person who made a mistake "deal" with it or "learn" from it or whatever. Mistakes happen, even to the most careful. There's no point in punishing people for it in a game.
