Earlygame / Previous Endgame Content Checklist?

For ARR to Heavensward https://www.reddit.com/r/ffxiv/comme...0_heavensward/

That should get you started. It doesn't cover everything from beyond 3.0 but is a good list of things to do and how to unlock. Couldn't find anything for 3.x to 4.0, but since you are only on Garuda EX this should cover a fair bit of the older content. I'll update the post if I find anything else.

I dont believe the above includes all side quests and such, like Hildebrand but is again a good starting point.
