Because I can and Klingon/KDF is my favorite fandom. We now have a wonderful tutorial and content to offer an alternative to playing fed and you can even go romulan if alien, klingon,LBklingon,wormthingy,reman,romulan,leathea n,gorn, those lovely orions, nauscicans, ferasin, and other races.
We have much to offer.
Show a sense of adventure. Everyone knows what the Federation is about. What a stale OLD story. You all realize that out there in TV land Michel Dorn (Worf) has be pushing the idea of a Klingon centric Trek series right? (He won't be able to use "Battlecruiser Vengence" but go Michel go! Make it happen)
Being Klingon doesn't mean that a person is a froth at the mouth if it moves shoot it type. (Thats what Fed TAC captains are for) Klingons love to fight, but they kind of insist on a decent reason for doing so. There is just as much depth and complexity to Klingons as there are with Japans Samuri class of the 13th to 19th centuries.
Play Klingon, and be part of making the stories, and the culture a real thing.
Honestly, I found the T2 Rom Warbird to be so terrible (both the free and zen versions) that I am using the T2 KDF BoP (zen ship) and rocked the house. The Rommie ships at low Tier have such crappy power output when put against the KDF or FED versions of the same Tier. Basically what I am saying is that the Rommie ships are not better at all. If I had to guess, I would say maybe it's your gaming style that is clashing with the Rommies.
Just be happy there is a third faction. A third faction that mirrors the KDF. It will only help to benefit future KDF content and patches.
The Romulans ships are not better, plus the Romulans have no Carriers or Hybred Carriers. Ground wise the KDF gets the Jackal Mastiff which awesome.
Don't follow your reasoning. My Romulan KDF aligned has access to every kdf ship that my klingon does. Being Romulan just allows for MORE ship choices, any romulan ship or any ship allowed by the faction that character is allied with.
