I have no idea, but assuming by the age they are in, the missles are certainly smart anough to track their targets and lazers are adjusted on the fly so its diffcult to miss, but the ships that shoot projectiles do seem unrealistic it almost seems as they are shooting smart bullets...
In principle, I would agree with you, however, I'm reading a series of books right now (Honor Harrington,) that includes Missile Decoys and Electronic Warfare. It also includes jammers and penetration aides (missiles that don't actually do any damage, but instead cause point defense to track themselves instead of the more deadly standard nuke or (what are called in the series,) laser heads.)
And creating a sort of point defense for missiles is another cool idea that I'm pretty sure has already been addressed. (with the ruling that it wouldn't work.)
Also, it should be noted that I am mostly concerned with missiles. I understand that lasers are instant fire weapons and it would make sense to only fire them when you get a lock or whatever. And I'm not sure how a person would go about tweaking autocannon fire to allow for maneuvers, so I'm not as concerned about that at this point.
There is another idea (that has also been inspired by this set of books,) of having a single big gun that fires (once again, within context of the series,) a focused beam of gravity that basically takes down a ship's shields, in addition to some smaller support weapons.
Unfortunately for the last idea, within this game, there really isn't anything to stop someone from simply loading up a ship with a bunch of big guns and turning them loose; at least that I have seen. I think that a way to develop your own ships (and, by extension, your own components for said ships,) would bring the game a touch closer to the 4X side of things. On the other hand, this feature is going to be only as good (read: balanced,) as the people who create these components.
