Shadowbringers has been widely accepted as the best expansion and it was written by Ishikawa. Then Ishikawa gave an interview about her plans for 7.0, 8.0, and 9.0 shortly after which was not what we got with End Walker and Dawn Trail. End walker's convoluted mess of a story to finish everything screamed of executive meddling where they shouldn't have been meddling and now Ishikawa didn't get to write Dawntrail at all. What do we get? Another "genocide is ok as long as it's not us" story and an underwhelming trial boss.
You have an incredibly talented writer in Ishikawa who could be reviving Final Fantasy's heyday of the 90s and you choose to get in her way then get rid of her?
Put Ishikawa back in the writer chair and let her write whatever she wants. No more executive meddling. Let the expert do her craft! PLEASE!
