This is a more casual fleet branch of Unrepentant, which is a gaming community of quite a few games.
As such - we may have a group in there rolling through every STF straight. Or, the group may be just doing leveling work. Some are even forming up a Red Skirt squadron for me to slaughter in PvP. (See how helpful they are ?)
So, not hard and fast answer there. If you are all about the STFs (Fed or Klingon) side, and no interest in anything else, we may not be a good fit for you. We certainly do them, and are very good at them, it just isn't a prime focus.
Sto'Vo'Kor fleet is a very "heavy" Klingon fleet you may want to check out, if such is the case. I have flow with/against some of them, and if your love/focus/desire is strictly Klingon, it would not be a bad choice. They are some good people over there, and tend to work together very well. (Which..great if you are a Kling, tends to suck if you are a Fed)
Best of luck, and feel free to PM if you have more questions.
