No because there are quests to kill mobs, so if everyone is doing the adult/master class quest at the same time, those zones with mobs will be crowded.

pretty sure adult quest and masterclass are solo instances, if you mean the quests to actually get to the masterclass, then yes, they are in the open world. To make it yourself easier, you will have to do the following:
Humans -> unlock majin area teleports.
Namekians -> unlock human area teleports.
Majins -> unlock namekian area teleports.
