I beta'ed the game and I must say is was absolutely by far the best game in terms of pure enjoyment leveling. There was never any bordom (except maybe the pie runs!). It was actually faster to level via quests... even the ones where you didn't kill anything. The only thing I didn't like about it was the addition of the party attacks, much like EQ2's system. And even worse... were only really used by the burgler (or whatever it was).
At an early stage I didn't see much chance that the game would have any real end-game content, as once they've exhausted the use of all the big shots from the books... where do the turn for expansion?
I did like the skill leveling system... the more you used a certain skill the better it got, ect. (Hell, if WoW had that system my healthstones from back in the day 40 man raiding would be GODLY)
