Hubs in XIV are underutilized

Edit:
You are also comparing scripts (something you had to do lots and lots of times for several things) with fun sidecontent.
A better comparison would be jumping puzzles and I see no one asking for them to be instanced.

To address your edit. There was also HW relic that involved Mor Dhona (depending on if you did the ARR relics), the StB totems, and other pieces of content that made go back to Mor Dhona. Even the bicolor mounts before DT require you go back there.
