Many valid points have been made on both sides of this and those points have been made alot in the 2+ years I've been here. (Man do I feel old now, oh thats right, I am old

)
I have seen my share of friends and guildmates leave this game. Those who leave and don't return have more than likely found a game where they are happy. Good for them I say, gaming is all about what you enjoy. There are others who will probably leave whether new content is introduced or not, it's the nature of a lot of MMO players to move from game to game. For the hard core MMO players who come here, this is simply not the kinda of MMO they are used to so they will leave as well. Some will and do come back when new things are put in game, when they finish the new parts they leave and will come back when the next new thing comes out.
There is no right way or wrong way to play or feel about the game. It's a game, it either provides the enjoyment we want or it doesn't. If you're getting what you want from the game great, I'm glad you are. If you didn't get what you wanted out of it and have moved on, I wish you well and hope you find what you're looking for. If you're like a lot of posters and are stuck somewhere in between, not getting what you want but still holding out hope that you will, I sincerely hope it gets here soon for you.
