The shard seers can give it magical+Eyeless sight, Ogrun give it curse and can repair it, it is hyper-accurate with guided fire, and can achieve a very respectable POW 23 melee P+S without any corpses.
Let the bloodgorgers be a solid first wave, and clean up with flailing tentacular goodness.
Just for sh1ts and giggles, Skarre also has shadow fire on her cannons, and deceleration helps everyone meet the battle relatively healthy.
She really seems incredibly well-suited to slaughter fleet, possibly even better than to scourge.
This is exactly what I had been looking at. It seems like a blast to play as well.
