Release days are always full of "fun" and "exciting" experiences that you will likely never get to experience again. One of these, was doing the "Boiling Blood" quest in Hellfire on release day with two guildies. There were so many people trying to complete the quest that mobs were respawning instantly, and people were spawning extra mobs from trying to actually do the quest. It resulted in my friends and I having a 15 minute stand off where we were all in a small cluster, fighting off a constant supply of mobs. Other people were dying left and right, but we were stuck there at a stalemate with the mobs since moving would cause us to aggro even more. The server solved it by crashing. Hopefully we can avoid things like this next expansion release...
