I agree with you, people need to stop complaining that they are getting free stuff (yes i know it was supposed to be in the original game but whatever, this is how it has played out so just accept it, download it for free when its available, and enjoy it).
Complaining that it is going to come later is not going to change that fact much, this is the hand we have been dealt so just accept it and enjoy the game for what we have. Not everyone in a game of poker is going to get two A's to start out with just how we are not going to always be given the 'best' game up front with all of the add-ons (maybe not the best anology but its what i thought of, if it doesn't make sense move on).
I know it would have been nice to have been updated earlier by the dev's that it was going to be later but the way people react to it seems like its the end of the world to them. Just because you are not getting your content (free content) right away DOESN'T mean your going to die. Play another game for awhile, lvl up your characters so your ready to work towards lvl 24, or better yet get away from video games and ENJOY life... instead of continually complaining that some add on to a video game is delayed
***Quick Edit***
Does it bother other people that when you come to check on the forums many of the 'new topics' are about the DLC or just negative comments in general?
