Hate is probably a strong word for this, but I dislike that the planet Endor exists as of ROTJ in the EU. The novelization's statement that the planet Endor had been destroyed at some point long before ROTJ is far cooler in my opinion.

Destroying planets like it was something casual is not cool... it is lame. And since you are concerned so much with OT uniqueness, it also degrades the uniqueness of death star.

For me, Endor is the thing we see in the background of initial sequence of ROTJ.
