Well, it seems a little bothersome that they intend to make it kind of Rift-like, in the way the of the events.
I'm not sure I want that massive, pug-events where no one cares a shit about you, just about themselves anyway.
Also the description about the lions... well, being able to read about the quest help in understanding why it happens, even though most of the time, I don't read anything anyway
Also it gives you time to get ready for the action, rather than the action falls on your head out of nowhere.
I also feel a bit sceptic, they said the same about Aion and Rift... it would revolutionize the whole mmo-concept and be a wow-killer. Neither happend.
Also moving away from instances, immediately gives me some warning signals.
But it will be hard to know for sure, until it gets out for real I guess.
