The treasure map dungeons definitely could use being doable unsynced, so you don't need to find a group for past expansions maps.

You don't need a full group of 8, you need like 3 people.
Treasure dungeons aren't going to be given the unsynced treatment for the same reason why Variant/Criterion dungeons aren't getting it.
