Naoki Yoshida interview @Gamescom

The issue with open world content is it just won't work with the game we have right now. Gear is upgraded very quickly. People zerg everything. We seen how hunts and Diadem worked out when it was a free for all and it removed all challenge. The only other option I see is if you have parties force a monster to spawn for themselves and possibly add some mechanic where the party could call out for help if things get too rough, but it might lead to zergs as well. It's a very delicate balancing act and I see why the devs just want to put everything behind instances; they can control how many people go in and design fights around that.

I totally agree and this could be done with place holder mobs to kill for the NM to pop, or Item pop, and also maybe finishing a number quest style objectives. Honestly though I would be fine with out a Help function as you come prepared to win or lose.
