This makes a lot of sense, I forgot about that. They're just the souls of themselves right now. Althought when Sargeras was captured it does seem like they have the power to re-size themselves (and others apparently).

That would actually be very fun! One of the things I enjoy most about MMOs is adventuring in new lands/taking in the new landscape. Would be interesting to see what gets left behind once a Titan woke. Although I bet Blizzard will say their planets are so far off from Azeroth it's not even possible.

Lands growing on them and such.
