Why can't we create homebrew classes

I agree. I want to make a shaman class with custom points called spirit tokens but there is no way of doing that except making it a subclass and then making the tokens as magic items or something and who wants the specialness of their custom class reduced to a subclass wannabe?

Its almost as frustrating as not being able to make magic ammo which really should have been fixed by now. 

NOTE: As a note it took me forever to figure out how to do this in Foundry and its sad that the player has to specifically use the Foundry char sheet to use it.
