I hear you ... it would need to be a reasonable amount of time on a timer. This might be a better alternative ..... if the AFK isn't in the Darkness Zone before the end of the timer, the group carries on without them. That person is then left to strike on their own. That way, the AFK might perpetually be stuck in the strike without completing it. People could join through matchmaking and carry on, but the AFK keeps getting left behind wasting their time since they're not completing the strike. Implement an event to slow down the runners that prevents them from running through without completing that event. :) I'd love to game with you, but I'm currently on the XB360. :( I'm waiting for Halo 5 before going to the XB1. I'd get a PS4 just so I can play some of their exclusive titles, but the boss (read WIFE) would have my head on a platter if I had 2 consoles. LOL
