That content wasn't created by Cryptic. Nero's ship engaging the Klingon Fleet is from the Countdown movie prequel. Cryptic just incorporated them into the STO Universe. If you have a problem with that plot,you should complain to the comic books writers,not Cryptic.
this is the first entry into the Path series that is plain incorrect, Nero has a Mining ship A MINING SHIP, now i know the Klingons fly in what barely passes for ships HOWEVER a fleet of Klingon vessels would DECIMATE Nero.
Seriously who is writing these things LMFAO you guys need to remove that log or atleast change the content because its plain wrong.
Sorry to say it but you're the one who's wrong. Nero's ship was, as already said, upgraded with Borg technology that the Romulans were working on in secret.
