Two problems with non-Tachyon Lance builds:
* They used to be viable, if not great, before the shield nerf. Odyssey still got clobbered by a battleship, but not as easily as today. Now that Conquest is stronger (more hull/armor, and more OP), it clobbers Odyssey too today.
* They are high-risk, medium-to-high reward. Among those, I have the best success with triple plasma cannon and claw wings, and success depends if claws survive AND disable enemy weapons. If they fail, Odyssey crashes and burns due to enemy outgunning it.
When Odyssey got its second flight deck in a later 0.8.x patch, its OP was unchanged. It was somewhat OP starved with only one deck, but now it is very OP starved. Talons are insufficient on Odyssey. Odyssey needs its fighters to make up for weaknesses. For a beam boat, Odyssey must use either Broadswords or Longbows for hard flux.
No matter what configuration is used, I always leave missiles empty. I also often leave a few small mounts empty.
Odyssey is also significantly starved of ordnance points. These need to be raised by at least 25.
ITU is worth 25 OP. Everyone will put at least DTC on it if ITU is unavailable. Just make ITU free and builtin like Advanced Optics is on Astral (and do not lower OP total to compensate since it is already OP starved).
As for the question of turrets. I am fine with them the way they are - at least they are not as hard to use Centurion's turrets. If there is a ship that needs better turret arcs, it is Centurion. However, I am also fine with Odyssey's turrets changed to make it easier to aim all three turrets.
If High Energy Focus is no longer useful after a turret change, and the system needs changing, I probably would want Reserve Deployment so it can at least compete with Legion on fighter power. Anything Odyssey is somewhat decent at, Legion does it better.
I would not mind a unique hullmod that made all missile weapons free.
