I have not beat the game yet so I do not know what happens in the end. A buddy of mine and I was thinking to keep the game going have new encounters side missions because the virus is still there and making new leaders of the factions new factions. Being able to go to the safe house and be able to pick up the new missions for that district would really keep the game going in my opinion. I do not want this game turning into destiny I enjoy this game a lot more and with what I've done and gone through I can't get enough. But with that being said things do get repetitive for people so having new things to always do could keep people involved in the game.
since the DZ is a pit of psychological bullying i agree that the grind of playing the daily missions doesn't help the emersion of this game. i like to wander the city and pick up little battle with the respawns but i am disappointed with the endgame. the DZ is a horrible place as i have zero to no interest in grinding for that illusive gold drops. I'm more interested in having interesting battles and if i go to the dz its purely for that (and to enjoy the visuals. Also i discovered that its better to head into the DZ at a lower level, the instances and battles are just as interesting and any rogue teams are equally matched.
i too was disappointed that the daily missions were essentially replaying the same pve game missions over and over. the PVE map is huge and i expected (or expect in the future) that the dlc will include different parts of he city.
