The Romulan faction is the only other one I wanted. If I get super bored I might enjoy a Dominion one though.
The Somraw, K'tinga, D'Kyr, D7, Kumari, Xindi carrier, Xindi escort, and the T'Varo are all older than the Constitution Refit and yet they are tier 5. The Constellation is made up primarily of Connie refit parts and it is tier 5, there is no logical reason whatsoever for the no tier 5/6 connie rule.
And now for the big kicker to all of this...IF Cryptic can work up the Romulan faction with leveling content from 1-50 AND add in additional leveling content for KDF to fill in the 1-20 levels and while doing all of this manage to add in new features, new rep system, new FEs AND new STFs with the majority of the work being done in 6 months, just imagine how much content they can generate for the "seasons" while moving the game forward.
Herein lies the problem. After 3 years the Klingons are a pale shadow of the Feds, both in content and the player base resulting from that lack of content. On the Fed side there are gaping holes in the content promised at launch and each season has brought more features and content that is only partially realized. Then there are the significant bugs and issues that have never been addressed.
Given all this, does anyone really expect a new faction to come close to the expectations mentioned above? And why would anyone want them putting resources into new things when they are so desperately needed elsewhere?
"I regret that we meet in this way. You and I are of a kind. In a different reality, I could have called you friend." -Romulan Commander to Kirk, Balance of Terror
" Counselor Deanna Troi: [as Major Rakal] We ensure the loyalty of the people. Do you believe the Empire would be better off without our protection?
Commander Toreth: Protection? From what? How was the Empire threatened by the words of an old man? A devoted citizen who merely tried to speak his mind? How did the Tal Shiar protect the Empire by dragging him, my father, out of his home in the middle of the night?
Counselor Deanna Troi: [as Major Rakal] Clearly your father was a traitor.
Commander Toreth: No. He was just an idealistic old man. I never saw him again."
-Face of the Enemy
"Admiral Jarok: There comes a time in a man's life that you cannot know. When he looks down at the first smile of his baby girl and realizes, he must change the world for her - for all children. It is for her that I am here. Not to destroy the Romulan Empire, but to save it. For months, I tried desperately to persuade the High Command that another war would destroy the Empire. They got tired of my arguments. Finally, I was censured, sent off to command some distant sector. *This* was my only recourse. I... will never see my child smile again. She will grow up believing that her father is a traitor. But she will grow up - if you act, Picard. If we stop this war before it begins."
And that's where the IP really fell off the wagon. It became too idealized, in an age where realism was wanted. TNG was fine, but by Voyager it was growing out of touch, and by Enterprise the IP had gone the opposite direction of culture at large.
