It is my understanding that the "choice" of new trilogy for the Galaxy's Edge timeline was Scott's.
Even with that choice,
@MansionButler84's points about the major issues with the land cannot be dismissed. Underbuilding ride capacity has been a HUGE issue over the last decade. You can build great things, but if they're unreliable or don't have the necessary capacity they need to be dropped down a peg.
They also missed the mark on the Smugglers Run ride film. The good thing is, that that's more fixable than a capacity issue.
It really is an issue of getting things 80-85% correct. Theming in Pandora is top notch for example, but I knew before ground breaking that ride capacity on Flight of Passage was going to be comparable to Soarin' with two theaters. How does that get approved? Na'vi River Journey needs another 2+ minutes of ride time. They also shouldn't be in the same building.
What's especially frustrating is that things like Seven Dwarfs Mine Train, Flight of Passage, Frozen Ever After, Na'vi River Journey and Rise of the Resistance opened after they felt obligated to increase capacity to things like Dumbo, Soarin' and Toy Story Mania.
