i think cryptic intends sci heavy kdf cruisers to come from the orians. i doubt an actual klingon cruiser will have more sci then tac. mirror vorcha is a bit of an exception, but it still had 3 tac consoles. very tac heavy for something with slightly more sci then tac.
If it's sci heavy, it might explain this quote ... "The Kamarag class was first designed in the mid-24th century, but only a few prototype vessels were built."
A HUGE thank you to Cryptic for the Mogh-class battle cruiser!
