"Routine" is an excellent word to sum it up. I'm convinced that the most ardent fans are also the ones with the deepest OCD issues. And I'm not joking. Only a psychological disorder could keep people doing the same repetitive tasks over and over. Normal people start to feel the numbness of routine setting in, and will seek variety. Maybe Bungie is just brilliant for understanding this, and giving those type of gamers something they can mainline. Personally, I'm not touching this thing again unless they put something fresh (and no, that doesn't include the reskinned Scrota and his minions).
