Putting aside TT rules for the moment [...]
I agree that 100% copying the TT isn't going to make a fun game, but sorcery points really are the core of what makes a sorcerer, a sorcerer. Making the sorcerer a damage dealer and the wizard a controller isn't unheard of in dnd history (see 4th edition), but it isn't how the class is at the moment. And besides, it adds depth in my opinion.
