And I would say a faction is their biggest thing yet. Its a faction, with unique missions for the Romulans and everything.
"unique missions for the Romulans" remains to be seen.
Here's what I think they did to get KDF to "full level 1-50 progression":
- Set character starter level to 1
- Move unique KDF missions from current 20+ levels, to follow chronologically after level 1
- New contacts, to run pre-existing FED missions in areas such as Regulus Sector Block, Pi Canis, Romulan sectors and Cardassian sectors
As a result, KDF -might- have unique missions for the first 10 or so levels, all of which already exist, just moved to a lower level. In other words, no new missions. After that, the KDF runs exactly the same missions that the FEDs have been running for the past 3 years, which again means, no new missions.
It may be a cynical or pessimistic view of what they may have done, but it would be somewhat logical in order to explain how they could "suddenly" have full leveling progression for the KDF. The same holds true for the new Romulan faction, with a handful of unique Romulan missions, and the possibility that they simply run the same missions as the FEDs, after their "starter area".
