My WoW account hasn't been subscribed for about 4 months now, but suffice to say all my WoWstalgia resides in vanilla release WoW. - UBRS - First time I saw a kodo wandering around Barrens (as a dwarf) - Dire Maul runs, then dashing outside when a rare arena boss spawned to do battle for the glory of fighting it. - First Epic BoE drop - First time being demolished by the very first giants in MC - Guild effort in accumulating +Fire Resist gear for Rags - Having a major quest/instance hub dropped in Silithus, when I was quite happy farming the humanoid mobs on my own. I can't think of anything noteworthy from TBC gameplay wise, just simply amazement at the new zones. WotLK had some great quest lines, I really enjoyed questing (and not power leveling) to 80. Unfortunately, I hit 80 with about 2 1/2 zones completely unexplored. WotLK endgame was boring.
