Oh you assume incorrectly. The E-wings design seems to be: lets take an x-wing, remove one laser and then put the other in the dumbest possible place, then, haphazardly bolt some engines on the wing.
Oh and that dumb laser placement? That is just so we can make a needlessly complicated seperation that probably results in wespons failure half the time.
Seriosly... Look at this picture from the E-wings' first appearance. Dumbest cockpit design ever. Also, for a brand new top of the line ship, it's covered in what is that? Rust?
