Doctor Who or Burning Crusade?

So I've moved on from FFVII (although I'm sure the urge to read/write about Tifa and Cloud will come around again). Did a turn with Kingdom Hearts both one and two, before getting caught up in the new Doctor Who series. Love Rose/Doctor, particularly Rose/Ten. However, as it happens...

World of Warcraft Burning Crusade is out. And I have two level 60 characters, a level 47, a level 46, and a level 27. Not to mention the new Draenai shaman who is only level 15. That's a lot of leveling to do. And there are soooo many new places to explore.

And I really should clean house, too.

So little time...
