Sorry but, THE GAR HAVE NO STORMTROOPERS. The only stormtroopers we've seen in the movies are the 501st legion, and they are leftovers from the Clone Wars. Clone troopers and terminate them, Fett clones have the best genome in the galaxy, natural instincts and ability are good but Dominion troops will lose because of the same reason Republic Commandos are weaker than real Mandalorians. Even though Commandos have better genes and natural talent, real Mandos have more hands on experience, so they have tactics that the Commandos never even seen before. So they are as Kal Skirata says "Data rich, Experience poor."
We never seen Star Wars adapt, because they didn't need to most of the time. Almost everywhere in the galaxy is explored and known thousands of years ago in the storyline, so there isn't anything new to adapt to. And when they adapt, they don't use enemy tech ( unless you count rebels using Star Destroyers ) they develop new toys, for example the YVH Hunter, ( Yuuzhan Vong Hunter ) Alpha Red, and the Fett-clone targeted virus. They are more than confident in their tech.
So there is NOTHING new in SW... they are at their technological apoch?
Good to know - makes it even easier for Trek, Stargate... hell, even Last Starfighter to steamroll em flat.
