I will say again I agree with overhauling the sync system in some way. Some content is unrecognizable in it's current sync'd form, even the 24 man's from Endwalker had entire phases skipped before the xpac was finished.

Why does this matter? The sync system was advertised to make old content feel as close to the original intent as possible. But when that system is letting you skip things in content that not only makes said content fun but is also somewhat current, then I think it is fair to say the sync system needs an update / adjusting.
