Have you seen a D'Deridex use single canons in this game ?
Have you seen a D'Deridex use dual beams in the show ?
Do we have any consistency with the show ?
I've only seen the NPCs use beams, just like every NPC Federation Cruiser.
[And yes they should move the DBB mounts away from the nacelles.
That looked stupid on the player Prometheus and it does on the Warbirds.]
And what can Federation Cruisers in this game use?
Dual Beams and Single Cannons.
So what exactly is your problem now?
*EDIT: you know as well I do that every ship in this game will end up with the ability to use Single cannons and Dual Beams*
