I remember when you died in EQ, you lost everything and it took two hour to get back to your body so you could beg someone to go down into the dungeon and drag your corpse back to you. If you were lucky that would happen, if not they would hide your body and yell, "Easter egg hunt!" Or remember when you had to wait 24 to 48 hrs for quest mobs to spawn and pray to God that you hit it first? How about having two mobs being too much for you and chasing you all the way across the zone or high lvls training massive groups on you while you were fighting? But now we have whole thread about a broken MOB for a couple of days or how phasing doesn't work because your friend and you did not click the same option when the wall of red appeared. I just shake my head at this foolishness.
On that note...what past MMO craziness can you remember that would have the players of today howling?
