In years past a lot of my friends, coworkers and guildmates have gone to BlizzCon and enjoyed their experiences. Some have forged long friendships there. All have gotten to play Blizzard games (including various WoW expansions), hang out with people and be social while discussing things they loved, and that's all pretty great from my perspective. I'm not much of a con-goer (I dislike crowds) but I think that's all pretty worthwhile, and is worth mentioning.
So now it's your turn. What's the good of BlizzCon? Do you enjoy lore panels, Q&A sessions, systems discussions? Were you filled with joy when reforging was removed? Share your good times please.
