No one more advanced than the Eldar, yes. Other points i agree on. But heres an example.

Say i have an empire, lets call them the Grammatican Empire. A human conclave that mostly survive the fall of the original Human Federation before the Age of Strife. They retained alot of their knowledge and for it have crazy tech, citys made of hard-light and other crazy stuff. But after some plot, they come into contact with the Imperium, including several Space Marine chapters. They fight, they lose, and are destroyed because of the Space Marines and the Imperium's while not more advanced still mightier forces.

Would that be breaking any limits we establish? Mind you it's just an example.
