The Herzog is an interesting beast... but easily decoyed; I'd actually suggest making some of its weapon arcs not full 360 turrets. Right now, if I cruise up to one with a "tank" type ship, every gun on the Herzog will focus on the tank - and its normal variants simply don't have the kinetic firepower to threaten that tank. Which leaves it totally open to being attacked by, well, anything and everything else I can field.
Narrower arcs for, say, the small & some of the medium guns would prevent it from focusing everything on one target, and make it much more capable of fending off multiple simultaneous attacks. It would also reduce the amount of firepower it was capable of throwing in any one direction, which might - depending on your reasoning - negate the need to remove a weapon slot.
