Battleship activation: All BBs by default will be restricted. BBs can be unrestricted at the cost of 10 VC points. Upgrades to a BB (B11K) can be unlocked for an additional 5 VC points. Each side will start with 10 VC points in the bank to they will be able to unlock at least 1 BB or they can choose to not spend the points to add to their score.
By "restricted" you mean unavailable in the yards?
And do you really think the B11K is such a bad ass that it needs 5 additional points to even activate?
Having it use up 100% of the capitol ships points is one thing, but, IMOP it isn't a "Super" BB as it's name implies.
It's more like competitive with the other races BBs that "Historically" were developed after the B-10, pretty much making the B-10 obsolete.
The B-10 is supreme when it comes out in 2273, far ahead of the other BBs (as the "Historical" timelines go), but, as other races come out with their own BBs, it's quickly outclassed.
And that includes the B-10K, too.
Match the B11K vs the Fed BB (which, by "Historical" timelines came out very late), you'll see what I mean.
