I'm not sure what you expected out of it. It was shown to be slower than the Galaxy in the shows. And bigger. It was always going to have a turn rate that made it prohibitive to play in this game. This game is slanted towards speed, agility and cannon based firepower. Since the D'Deridex won't be a carrier, it was always going to be too slow to compete in this game.
The D"Deridex was also supposed to have more firepower then the Galaxy, which is why Picard was always hesitant to fight one solo, and prefered to talk, or have allies like Klingon Vorcha's show up to help. I don't think the Enterprise itself ever managed to solo a D'Deridex.
So while I would like a little better turn, that is not the main fault I see in it, I am concerned with the boff layout mostly. I know this game is slanted towards cannons, I use DHC on everything that can mount them, even a Bortasqu, I am experienced enough to make slow turn ships work with DHC, but I can't do it if it has the horrible boff layout of a Galaxy. If they are going to make the ship have bad turn, it better get 5 tac consoles and Lt Cmdr tac at least like a bort does.
Thats not enough. It needs 5 tac consoles, or 4 tac consoles and sensor analysis, and a super weapon console that can deal massive damage like the autocannon, and some type of universal boff station. The only thing that makes a ship with turn as bad as the Bortas worth flying is those features, and even then, most players still can't put up with the turn rate.
there i actually no reason why the D'Deridex has to be any slower turning then the federation galaxy class because yes the D'Deridex i twice the hight of the galaxy class. while the D'Deridex is about the same total weight at the galaxy class because of the massively large open sections between the upper and lower wing and the romulan warp/quantam necells.

its pretty obvious where the devs interests are.
unless the deri gets re-branded it will get scudded hardcore, because if it didnt there would be no room for the excuses used to leave the big ships in this game as targets for ships that amount to being star fighters. and no excuse for leaving similar sized ships so out of whack with each other just to keep the bogus 'class' stats.
as it turns out, an intrepid would lose a fight with a connie. and thats canon.
! the power of plot compels you.
People need to calm the eff down. What's on Tribble right now is very unlikely to be the final stage of the ships. You're all in danger of working yourselves into another foaming-at-the-mouth frenzy about the Romulan faction being shortchanged, just like you did with the announcement.
Just sit down and watch, stop speculating yourselves into disappointment.
