Frith, let me disagree with you in one point:

We do not have endgame content?
So what do all this vet players do (who are the majority and who log in every day for hours) all day long?
I play endgame content since I entered Order many years ago.
And I`m always busy-and so are my friends.
Endgame means too, that you can do what you like
and not what you think you have to do.
And all that patches and content updates keep us busy.
Playing everything that the game offers ( and yes, newbies or less experienced players do not know all about that, which is a pitty) is the hidden secret, why we have so much vets here. There is lots of endgame content, often available for lower level too.
