I never played XI but I have experienced the whole go to a point and wait for "insert monster name here" and hope you get the claim on it. I hated it then and I'd probably hate it now. Being social with my FC/LS members isn't enough of a filler for me to wait on spawns, sorry. With that said I do like the ideas though.

I think there should be NM mobs from the levels 1-50 and each kill should be added to the achievement log. It would be cool of each major zone had titles, pets, and vanity stuff for x amount of kills. On top of that each one should drop something awesome for that particular level but I don't think it should be anything raid equivalent for level 50. It would be cool if some of the drops were for crafting certain things for player housing or cool pieces of gear. Possibly drop something of the DL equivalent gear wise.

Going off the contribution system in XIV if NM is implemented most, if not all, will probably be tied to the fate system but that doesn't mean SE can't make them dynamic and fun even with a large group of people. To keep with some of the claiming theme though for the people who DO enjoy that thrill whichever group gets the claim should have percentage chance to get w/e item drops. Personally I do not want to see all of them tied to a fate though. Just because I do not like spawn camping doesn't mean some of the NM shouldn't have a "fight" over a claim. Variety is the spice of life after all and people can't be afraid that everything implemented will be bot infested when it comes to the open world.

Are 'pop nm' where the nm drops an item and with that you can spawn another NM only your group can do?
