The fact that you can form an effective group to fight any of the individual NMs isn't the point. They're randomized between all 22 jobs, and some of the jobs are a lot more problematic to fight than others, and there doesn't appear to be any personal reward attached to killing them. Unless I'm mistaken from reviewing everything that's been said to this point, the reward for killing them is server wide on the following conquest tally. There is no incentive to kill them yourself when somebody else is probably just gonna do it for you.
Fighting Volte Nms is one of the fastest ways to delevel your mastery ranks. Fighting Volte Nms for no personal reward when you can just let someone else do it for you is just a stupid system. At least give us 2-3k temmy/appy points for killing them or something. It's hard to justify constant exemplar penalties without that kind of incentive.
