Inevitably I think people will find a way to go as little as possible. Is like cheesing bosses. People will always find the path of leasy resistance. Unfortunately I don't think the solution is easy or even possible. Even if you make it so they participate in every darkness zone people will find ways to do nothing while being in the zones. And in the other hand, putting in a kill to earn loot system sounds good initially, but I have had a few friends that I wanted to help get higher level so they could raid with us and dragged them through the nightfall and weekly to do it. Now think about this.. So many people complaining about afk people on strikes. Imagine if there was matchmaking on the raid and we had to deal with crap like this? Point is that this stuff isn't a flaw in the game as much as in the gamer. We just have to learn to live with it.
