Edit after seeing Sig's post:
The only thing I can say to the first part, Sig, is that I think you are seeing something that is not there and assuming it means an inability to produce it, when it just as well could be the case that it was intent of design and purpose for the fleet. Also, for means of completion, the Nids battleship is a base 10 hits as well.
As to the Hero, I consider it a failed translation of fluff to rules. According to its fluff, it is a grossly overpowered vessel.
Comparing to the korvattra in general I think is a mistake, as it was based on a totally different design philosophy.
*End Edit*
Half of what you wrote doesn't even make sense to me Horizon. One can't simply 'move away' from an engagement with slower speed and hope to gain an edge from it, and the Carnage will always have the positioning advantage.
But we have both submitted our best points for the HA to review. (whenever they get around to commenting)
And, correct me if I'm wrong, this is what we have so far, that everyone at least mostly agrees on.
I beg with dignity the HA to playtest the following, as I will. (Someone PLEASE pm me so we can game!)
Custodian:
Tracking system range increase a must.
Needs either cruiser status or 90* turns.
Prow deflector or 4th shield, option or standard.
And the issues we DON'T agree on:
Points cost of Protector
Strength of broadsides on Protector and Custodian.
Points cost of Castellan.
Worth of Viorla variant.
Thats all I can think of. Another Protector and Custodian variant would be give some fun and diversity, but I guess that could be left to house rules. I know I will certainly be playing the Kororvesh the correct way, either way
