Hmmm. 6 was about a about 2 weeks, 7 we completed in 2-3 weeks and then 8 we were just under 3 weeks. We haven't had the chance to really put in time into 9 like I would like since we were needing to replace 1 player who lost interest in the game. He's playing destiny with his wife on ps4 now. One of our tanks wanted to move into a more hard core static, which I can't fault him for.
