I recently got to Veteran 1, 3 days ago and have just finished up all the main story lines and have started progress in to the Adventure areas for Veterans.
I have also read the information about the new content patch due out at the end of this month and I have to say, I am thoroughly impressed.
I understand a lot of people have encountered bugs and issues along the way, but without giving to much away, believe me when I say this, this game has a massive amount of content on release and in my opinion, content is king and is what keeps people playing.
To those possibly losing interest due to bugs, stick it out, you won't regret it.
Just remember, Level 1 to 50 is only 33% of the game and that's not including the Storyline and Guild quest series.
