"Blue" (what we call any blizzard employee forum poster because their text is in blue - in this case Nethaera) started a thread on the official forums about preparation for the Burning Crusade.
I'd link it here, but Blue posts have the tendency to grow large, break then disappear. Anyway I've copied it here for posterity:
For those that are getting the expansion, what do you look forward to most and how are you preparing for it?
At current, I'm doing some last minute rep adjusting, storing away a few items I know I'll need and pretty much enjoying the hustle and bustle of everyone else.
Some players are farming cloth for bandages. Others have been mining so they can level up jewelcrafting. And some are working on Exodar/Silvermoon reputations - for mounts I guess.
Someone mentioned reserving names for their brand new blood elves and paladins. I'm glad they mentioned that, because in the past I've spent literally an hour thinking up a name for a given character. If I go ahead and get that out of the way now, my friends won't be waiting for me in the starting area while I sit at the character screen wondering if this name sounds too exotic for a alien race and if that name sounds to valley girl for a pompous elf.
I have mixed feelings about preparing for BC. Anytime I start planning I feel like I'm taking a game and making it a job. On the other hand, I'm the same player who saved gold from the time she started her second character until she hit 60, so that I could buy an epic mount as soon as I dinged. So I know the value of preparing, stockpiling and saving. Work before hand saves time later.
But still, sometimes I think, its a game - why don't I play it by ear? If I feel like farming runecloth (for some crazy reason) so be it. Otherwise why spend time doing something I'm really not up to doing, just so I can level up my first aid to 375 as soon as I enter Illidan's realm?
If I'm a grasshopper now, will I envy the ant in the Burning Crusade?
