I never really thought about this, but I had planned to make some log entries, much like the Federation side, on my Klingon character(s). I also was looking forward to doing this on my Facebook page (however that turns out; since it still is not working in-game).
Stories of blood lust and the like and maybe some humor.
Now, I know there are still many things to do: PvE content for Klingons being a main one, but I was quite surprised I couldn't even create a basic log or add a supplemental one to my Klingon character. I am also surprised I missed this for so long (I guess I've been PvPing too much! :p )
