Level syncing hunts hurts solo players who don't play at peak hours (I like to hunt ARR and HW A ranks at like 3am because there's no competition) and also there's at least one Big FATE that isn't level synced, and that's the Behemoth one. I was always sad thinking of that FATE because no one's ever around to do it, but I learned the other day that I could do it at level 70 and got a full party together with a couple stragglers and were able to do it, which is much more preferable to waiting for like 50 people with FATEs like Odin (unless they've changed that too) and stuff.

The idea of getting an instance fight with said monster is fine to me, because at least everyone has a chance to fight it, but please no level sync. I like that I can switch to my level 70 PLD and safely fight most of what I encounter.
