Some more thoughts while we wait on HA comments.
In playtesting, how have the Protectors stacked against, say, Lunar cruisers. Its 5 points more, and I don't see how it wins its engagements.
One thing I vote on, because a cruiser with 90* still has difficulty getting that front arc after the pass, is to take 4 of the Protector's frontal batteries and move 2 to each l/f f/r battery. It currently has pitifully weak broadsides, the emissary's are stronger.
Thats all I can think of right now, just want some play knowledge.
