Well, I'd love to get into the lore more often but I feel that it has it's short comings and holes.
For instance, one of the lesser known links between Proph. and EotN is the quest,
Unspeakable, Unknowable. In this quest, we retrieve the
Tome of the Rubicon This tome is an ancient Dwarven artifact that is
buried deep within Sorrow's Furnace. The Tome holds
the true name of the Great Destroyer. In the quest Unspeakable, Unknowable, the Stone Summit seek to unearth this Tome and learn the true name of the Great Destroyer to use it for their nefarious purposes.
High Priest Alkar enlists the aid of players in stopping them and burying the Tome deep within the ruins of the Stone Basilica.
Now, before EotN came out I thought to myself, "Wow, this is awesome how they can take a small facet of the Proph. storyline and create an expansion from it, filled with it's own lore. I wonder who exactly unearthed the tome and uttered the name of the Great Destroyer. Speaking of which, I wonder what it's name actually is."
Do we ever find out who unearthed the tome?
No.
Do we ever find out who uttered the name of the Great Destroyer?
No.
Do we ever learn what the true name of the Great Destroyer is?
No but we find out who his boss is.
Does the EotN dialog even mention the quest which it was based on?
No.
Other questions were also left unanswered but it's late and I'm too tired to list any more examples right now. I think most people here can understand where I'm coming from with this. Like I said before, I'd love to delve more and more into the world of Guild Wars but it's shortcomings leave me less than appealed.
EDIT: In b4 "Wait for GW2."
