Hey! Sorry I'm so late to the party!
I'm at work and studying for a midterm, so my input for the time being will be limited to the fleets I play.
First! The hero. IN seem to disregard fluff every now and again, however with one 2 cruisers, I suppose having this one match is important. That being said, if we're set on making it weaker than the lunar (which is fine, also I don't have the pdfs with me, so I don't know what it's actual stats are) it should get at least a nominal point adjustment (down).
Second! The hellebore. I've used the varient with just fighters, and I probably won't pay 80 points for it, ever. I had it with seekers of the dark city, and even then it was marginally useful at best. I use hellebores, I like them, they're never dominatingly powerful, but they pay for themselves. I will probably not use them at 80 points, they just don't inflict enough damage to warrant it, in my opinion. So I think they should still be 75 points, OR get bombers, though that may require a further price hike...
Last but not least, Talos' suggestion of bombers for the protector. I like the thought, but I've never ploayed with the protector. I hate the thought of just having a fighter in the bay of an ordnance centric race though. Could include bombers with a cost/restricted varient.
Feel free to ignore all of these, I'm late, I know. I would also like to look at the torpedo gun boat thing from nemesis, but I've gathered we're saving that book for later?
