EDIT:
With the notable exception of the EU being scrapped
Disagree. I think that EU being scrapped was the right decision. Imagine if the ST had to be bound to the EU. Would make it a lot worse in my opinion.
Of course we wouldn’t keep the entire EU but if Episode VII had revolved around the Thrawn Trilogy it could have ended up being a better film. Also if we remove ourselves from the PT - ST eras the Old Republic Era didn’t need to be scrapped. There were plenty of great stories they could have preserved while leaving room for new canon stories to be told.
