It also ties it to a book, if you need a book to cast magic you aren't really a sorcerer anymore, I don't get to feel like magic incarnate if I have to carry a spellbook. (And don't you need high INT for it?) It is not more acceptable than just play a wizard. And if I felt comfortable playing one I wouldn't have this problem -but really I can't empathize or even get into the wizard mindset-.
I meant Rope Trick. but shadow ponies and summons are also missing.
You need Int for ritual caster
The bloodlines -like I don't blink ever, I turn blue, or I'm covered in scales- are the things making you inhuman looking. Besides, this only covers one character, how about if I want an elf, or an Aasimar? or a Gnome? or half elf? Remember this is not a single character, it is a type of character of which I like to play many.
