It's been a while since I played it but I'm fairly you that in DOS2 you could travel to any waypoint from any location as long as you had it unlocked and weren't in combat.

People like to blame publishers for all evil in the world, but in reality it's just an inevitable outcome once a studio or franchise becomes big enough to stand on its own legs.
