You dont need 2 torp spreads. I would swap one out for high yield.
I like to do the torps abilities with the cannons. So i use canon rapid with high yield. And scatter villey with spreas. This usually gives me the best shot at makin sure shields are down when torp hits.
The rest of the build really good. Just keep workin for those mark 12's.
For doffs i use the cannon abilities and torp cool down doffs. And i have a boff cooldonw doff. I do notice a difference.
This just popped in my head. If ur worried about shields maybe try moving ur mvae console to the tact spot. You lose some dmg but you can then get another field generator.
