Level 100 is around when you can start fielding a full 6 star team anyway. People in JP do it at lower levels but they can't get their rank very high unless they get carried.

I'm guessing the level 100 requirement is to prevent too much strain on the servers since it will require a constant connection rather than instances of connections when doing ordinary quests and vortex.
