As for me, I have a pretty terrible memory, but I do dimly recollect taking tailoring on my first character, a Hunter, because I'd heard about shirts and they sounded cool. But that fits more in the "noob" category than "old-school" proper. Inner Fire raising attack power and not having charges? Throwing weapons that couldn't have their quantity refreshed? Reck bombs? Decursive? I haven't been playing since beta or anything, so none of this is too crazy. What's your favorite memory of WoW past?
