It's true that we have many threads on this topic, so I'm always worried that some of the feedback might get lost.
https://forum.square-enix.com/ffxiv/...-full-spoilers <- This thread is very comprehensive and also has linked to other very valid feedback!

The japanese playerbase has a single thread with a lot of valid feedback as well. They have done a great job pointing the flaws out. If you're curious: https://forum.square-enix.com/ffxiv/...81%84%E3%81%A6
Running it through google translator is often times enough!

Mentioned feedback is story focused. Most flaws have been pointed out fairly well. The fact that Yoshi-P still failed to address core issues pointed out in our criticisms is worrisome for that reason.
