Q u o t e:
The Death Knight starting area usually takes a good hour and is very well thought out, the echo isle just seems to be a bit of a rush.
They're not really comparable things though. The death knight starting area is as it says on the can, a starting area -- whereas these are two fun little events that precede the creation
of the Troll and Gnome starting areas that will be in Cataclysm
. And believe me, those starting areas take much longer and are quite entertaining. :-)
These aren't the only things that will be going on in and around Azeroth in the twilight before the cataclysm... ;-)
