More of the same, but who said thats a bad thing?
It's going to take you a while to get to 70....and it's not going to do your homework while you are getting there. There's no point going into detail about this expansion pack. If you already play WoW, (unless you live under a rock) you've known about this expansion pack for ages, and have known all the details as they have been revealed in the build-up towards the opening of the portal. Basically, get the trial of WoW and see if you like it. If you do, go out and buy WoW and Burning Crusade and play it. There is no reason for anyone who has an existing WoW level 60 to complain about this game. It's simply more of the same of what everyone loves, and it works!
But, unfortunately, as I hinted at above this game wont do your homework. Moderate yourself because its going to take away ALOT of time, trust me. Or maybe dont buy it and live your life...your choice. This game scores a 8.7 from me because it's a good game, regardless of the fact that it's kind of addictive and takes alot of time away.
I spose it is up to you to decide wether you want to involve yourself and become dedicated to it.
