My guess is that you won't be able to branch out. Your starting class will determine the Tier II and Tier III Disciplines you'll learn.
However I think that the main complexity will come from the evolving Disciplines powers. While we know what to expect for Kai Masters and Kai GrandMasters, Mongoose has to do the same for the other classes !
