Balance wise, I would say this: Dreadnought Hunter is a waste. If you position a ship so that it is both in the fore and side arc, you have a base 60% chance of causing a precise shot (inflicting a jam token or disabling a hardpoint), so carefully positioning a ship goes a long way to accomplish the same goal. Meanwhile, Dreadnought Hunter needs to be equipped by an initiative 4 or higher, which implies that in order to be useful, you need to have an ally take down the shields first, so that means sinking even more points in other initiative 4 or higher allies.
So far, with a cost of 10 points, I would rather put a lot more initiative 1 units than sinking points in that upgrade. Balance wise, I think this is the clearest one that could use a change.
