The following is my opinion only and may not represent the opinion of the team as a whole!
I was thinking about new currencies to pay the folks at those stores (like e.g. faction points which you would also gain by doing missions so you are not forced to do PvP when trying to get those rewards). Like PvP rewards in other games, however I am a bit unsure about that. A crucial point in my opinion is to make sure that the best weapons and stuff is still obtained by trading with players. What do you people think?
