If they don't up the difficulty of the NM's and mobs in the dynamis zones...

I don't forsee a problem with people overcamping NM's... because they will probably die really quick...

However it does bring up a good point.. people could try to grief or w/e by holding a time extension NM or a zone boss / attestation NM.

So maybe have the "Confrontation" status only last 10~15 mins and the NM despawn after that automatically.
