Why thank you!
Many of the reasons I state are all due to watching other s play, or discuss them as well. That and well, just how much information can you fit on a single page? I am going to say, it is in fact safe to assume, not much. It would probably end up with a super simplified method of combat and actions, in which you will find arguably engauging or not. With little to nothing to write down, there will be less substance and by in nature it would not feel like the character was anything more than a piece of paper.
That said, there was a call for an opinion. I gave one, I never claimed to be the authority on the subject.
