[Captain Kwok]

One of the things to keep in mind is that with adding weapon arcs and facings, you make it much more difficult to balance individual shipsets. Unlike Starfury where you might have to balance a dozen or so ships, SE:V has about 150 to worry about. With the directional damage, once shields and armor are down (or special damage types are in use) it plays a minor role such as in a pursuit, where a fleeing ship tends to be hit in the engines first etc. Lastly, fleet battles tend to end up in melees anyway, so if most of these features were active there wouldn't be much difference in the end result.
