Better fighters need a system for passing on experience

What if the Galactic Empire replaced ordinary TIE fighters with TIE Avengers and rotated veterans into training posts?

The Rebel Alliance would face a much harder air war because better aircraft would be paired with an institution that transfers combat experience to new pilots.

The fictional Empire receives a more capable fighter and a better personnel system. Rotating veterans into instruction prevents hard-won experience from disappearing when individual pilots are lost. Rookies would enter combat with lessons already distilled from earlier operations. The Rebellion would struggle far more against an opponent without the Empire's familiar quality and training weaknesses. Equipment and institutional learning multiply each other's effect.
