I am pretty sure this has been suggested before but anyways.
I was thinking it would be cool for knights to explore the surface. not sure how they would fit it in the game since its all about getting to the core. maybe missions like find the ship and establish a connection or have it be t4 or something. opinions?
They could even have like a partially open-worldish sandbox room. Large like the haven, maybe bigger, with simple enemies, just where people can hunt and hang together. Good way to pass time while waiting for mist to regen or even get tiny amounts of cr or even maybe less rare materials? They could even incorporate small errands to run for people on the surface, not as complex as missions though :) And if they wanted to keep it fresh, update it every few weeks.
