I'd rather see a Conquest or Expansion system. This does not mean all mission have to be purely combat based, though to not have some combat would be odd to say the least. Think about the "Aid the Planet Missions" for the Feds, now think about something similar, but with e KDF spin, much like the episode "A Private Little War"
I have a partially finished mission on Tribble that's basically you as a KDF captain annexing a star system. I would love an entire gameplay mechanic based around something like that.
sure cryptic has thrown in some wild stuff, stuff that one would never have thought to appear in the star trek universe.....Klingons and diplomacy do not mesh...another reason is, KDC does not have that ring KDF does.
