The concept with big ships and fighters around it derives from old good WW2. But yes, if we came to the factors there wouldn't be any need for fighters in space - like most of military sci-fi titles, no matter if books, games or movie, share the idea - because it would be a risk for a pilot and waste of research time just to figure how to make life support small.
However, in current age of electronics, there's a possibility that huge vessels may be either controlled only by few crew members or even one person, yet we all know that the technology used in current space age (not sure about Chinese one, because we don't know what THEY have) is more like 10-20-30 years old, because of the reliability.
According to the big article about warfare in space, only big vessels would fight each other, but the problem is they would need to be very agile, if the lasers will have suitable powercore (leaving the miniaturisation away). But the laser idea may be bad because what if the hull had big mirrors? There's also the missile idea with nuclear device onboard (nukes in space behaves differently than on the planet), but either weapon or tech we use, crew onboard would be really in trouble...
