Without getting too much into the lore, you may recall Mount Hyjal as being a pretty pivotal place in the history of Azeroth. It was there that the Battle of Mount Hyjal was fought at the end of Warcraft III, and the destiny of the night elves was forever changed.
We've known for awhile now that the Burning Crusade will let us access some moments in Azeroth's past, including Hillsbrad, the Dark Portal, and Hyjal. What we weren't really aware of until now, is the apparent gargantuan effort it's going to take individuals to get ready for and attuned to the Battle of Mount Hyjal.
Blizzplanet has a rundown on what you'll need to do in order to be admitted to the Caverns of Time for this epic event. Keep in mind that there will be some spoilers in there, but I believe it's worth the read just to get a grip on what Blizzard has in mind for us to get ready.
This is not like getting attuned for Onyxia or BWL. In fact, this seems like it's a bigger deal than the AQ40 event was, on top of which every single person in your 25-man raid group has to have completed all the steps.
Personally, I think this is pretty cool. Instead of slugging through raid after raid, you get a big build-up to that raid. No more walking into a giant event without some idea of what lead up to it. I think this shows that the Blizzard developers are thinking about the world they're creating, and the lore behind it. This can only be good for the continued success of the game, and I'm sure it works as a nice timesink for the beancounters, too.
What do you think of lengthy prerequisites and jaunts around the world before being let in to a big raid event? Does this encourage you or discourage you from pursuing quest chains and following the lore?
