Yes, one of the more depressing things I did recently was level up a new character in WoD after having not played since pre-Cataclysm, basically. Going back and soloing instances that I remember grinding for months and months, encounters I remember working out for the first time with my guildmates (no videos or strategy guides!), bonds I made and the sense of achievement we all had at the end... totally destroyed by a fifteen second punch to the face by my brand new level 100 character. Though I wanted the gear for nostalgia's sake, it wasn't worth the heartache.

It felt a little like going back to college a couple of years after graduating, where a layer of nostalgia wasn't enough to disguise how much I, and the place itself, had changed. (Because college, like WoW, is a lot more about the people for me than the physical buildings.)
