The "deflectors" label strikes me as a little confusing. It has semantic overlap with "shields." Why not just call it "agility"? You're already just one step removed from that anyway, since the implication seems to be that the deflectors allow the ships to leverage their agility to avoid shots. Then the counter to agility can be explosive missiles and flak, since you can't dodge the explosion.
And then maybe it'd make sense if "bombs" were actually torpedoes, since people usually expect bombs to do area damage, and AI War ones don't? Maybe not so much since there's a pretty strong sci-fi tradition of "bombers" that just attack hard targets, but that's not universal.
On a slightly different note: are shields fun? They seem to make battles a lot more binary - if the attacker can't kill the shield they make very little impact. This seems to me like it's pretty negative both for defense (where your defense frequently crumbles based on whether the shield drops) and offense (where shields can cause incredible grinds). Would the game be better if they just didn't exist and things were however much tougher?
When I read about them the first time, I thought squads were going to be a collection of ships, letting you group things into one unit. Reading this document, I'm getting the impression a squad is actually just a ship. Is that correct? That's perhaps a bit disappointing if so, since grouping things together and having them fight as a unit sounded interesting and like it could make other things, like what ships the AI actually has on the game field, clearer.
The document seems light on detail about how defenses will be more interesting, or how the UI will be improved. I think the UI especially is one of the things that could most benefit from improvement and I am sure people would love to hear about it and also that if you do anything really interesting it'll cause controversy.
Anyway, it's an interesting document, but people are right that you could cut out all the technical stuff, or at least refocus it on the user experience. NAT punchthrough or lidgren are boring, but multiplayer working more seamlessly and smoothly is awesome. Multithreading is boring, but bigger battles than ever before would be awesome. And stuff like that.
