And how is this a bad thing? You fight these NMs to obtain the items they give, not to have hours of entertainment. Even difficult fights get boring eventually.(In FFXI) Al'taieu and Tu'Lia's NMs were a blast!... the first few months. And those were not even the worst ones, as you had to walk around the zones and they had a few, poppable NMs instead of just one [Khimaira, Fafnir, Cerberus, etc... (biggest waste of my time in my life by a long shot)]. Missions entertain, they flow and take you through different places; you interact with NPCs and fight new, mission specific NMs and so on. But NMs are just that, a monster. It will get tiring, so why stretch it when you can just go fight it for what you want, get it and then move on to better stuff?
