Ah, but my point is that you don't need to force those roles.
They come naturally given the appropriate components, and it allows a lot more freedom of design for the player.

The autofiring ability of point defense is the big kicker.
You always get to shoot the missiles, and the only way to get hit is to run out of shots.
Simply removing the autofire makes combat far more interesting, and missiles do not need to be uberly powerful and plentful in order to be a threat.
