Grinding gets boring, so does mindless questing, for the pve infatuated.
ZOS you have the basis for random events there. Daedric anchors, daedric tears.
Why not use them like rift, uses its rifts for big zone events.
Have big daedric invasions. Have squads summon from anchors and go walk around. Have tears open and mobs drop in and go attack random stuff. The foundation is there, use it. Would make things far more interesting and keep people on there toes.
