Well there was PvE content added yesterday as part of the Season One update. I cannot vouch for all levels but Brig Generals have PvE missions in the Azure Expanse that grant Exploration Medals. These are dailies though. Also there are several other missions that were rehashed Star Fleet Missions for the KDF side. I was only able to do the dailies and try the new "Cure" mission though. Maybe someone else can comment on those.
