acceleration to experience has some grumbling "I remember when you had to grind your levels," a la Grandpa Simpson. In fact, for those who have been playing the game for a couple of years, nostalgia not only kicks in, but a little dementia as well. The_ivorytower recently posted on the WoW LJ about this very topic, about all those moments that add up in WoW to just make you feel just plain old.
Among the things she brings up are those times in long past when spells like Consecration and Evocation were talents. Or how about the Unending Breath that never actually ended, allowing the Undead to sit underwater untouchable by their opponents? She mentions also Mor'Ladim and his insane aggro radius; he would basically run straight at you once you set foot in Raven Hill. And the Sons of Arugal that would descend in a pack to pick your bones clean in Silverpine before you even knew they were there.
Because this game has changed so very much since launch, often times you can date yourself from the elements you remember before they were removed. Plains Running anyone?
