You know what FFXIV should take from WuWa?

Companion stories

Give me 1-2 hour long short stories about each of the Scions, like a Y'shtola companion story. Use these stories to really flesh out their characters and endear the players further to them. But do what WuWa does, which is creating entirely unique mini dungeons for each Companion story (with entirely new assets), which is something I really love about Companion stories in WuWa.

FFXIV would just re-use zones and dungeons we've already been to and play Machinations 50 times.

For example, look at Cantarella's companion quest, it's about 2 hours long and you spent most of it in an entirely unique dungeon that only exists in her companion quest, culminating in a boss fight against a boss that was an entirely new model at the time.
