A lot of people are talking about putting in challenging HNM-type open-world NMs. I haven't tried to do it recently, but did they change the "anyone can attack anyone else's claimed mob" thing? Wouldn't this just be abused if they put the uberest gear dropping from free-range mobs?

Seems like it would just be 50 people on one monster, and less of a real challenge.

I'm all for the open world NMs dropping amazing gear.. I think people should have options, but seems like it would take a lot of the fun away if there were five parties all fighting the same mob. Like sorta just standing in line waiting for your meal ticket.
