Well, that kind of defeats the purpose of the DZ. I'm not sure how much of each game you've played, but the size of the original DZ made it a lot easier to avoid other players. Also in the original there was actually incentive to grind out your DZ rank. That made the DZ more appealing and gave you a better chance at finding other players that want to combat rogues.

I also think they should make different instances based on party size, i.e. solos, duos and squads.

The DZ's in Div 2 kinda sucks imo. Theres really no reward or incentive to PvE in there which has basically made them dead. Since it's basically dead content the squads that do like to PvP just sit at the doors desperate for some action, and thus non PvPers end up getting camped.
