I am doing this in bullet-point fashion because, well, some people don't bother to read anything longer than a tweet.

1. Please bring back similar FFXI-style NM with various pop conditions
2. Please have the rewards be based around trophy items for display (maybe Jaggedy-eared Jack's head as a hat)
3. Please do not put stats on these items, therefore making camping ENTIRELY OPTIONAL AND NOT CENTRAL TO GAMEPLAY MECHANICS
4. Possibly incorporate crating into the concept by turning said drops into trophy item/gear

I started a similar post that was derailed by people who could not grasp #3. Other posts we're also derailed because of this and also because it contained an XI reference. This is more simplified and directly clarified version.

Please keep the posts on-topic.

Explanations below (if you want to read further):

A. Some people want hardcore content, others do not. This is the best solution that I can see as being rational that does not infringe upon the choices of others. Making an NM drop a diesel ring invites botting, hacking, and poor general treatment of others. Sometimes none of these things will happen but the game is a world of minimal consequence (much like these forums) so weak-willed people will likely take advantage of the situation to reinforce an ego that is already fragile.

B. I enjoyed the experience of camping these and a useless but cute reward would be neat. Others don't care about the same experience or rewards so the mechanics should not penalize them.

C. This is an alternative mechanic similar to the request for card games or gambling houses. People are running out of things to do and this is a pleasant option for many of us.
