I know alot of players who have quit. They're all still in my friends list and I see them playing other games or watching movies. Since I'm retired I played a ton out of the last IB and there were several matches where it sent us in 4 vs 4. I've waited 10-15 minutes for IB matches to reach 6 and had to back out and try again. I've also had to wait for weekly heroics to get 3, hell, or even ROC strikes to reach 3. I suspect it'll pick up again once we get nearer HoW. Cheers
