Nice Post.
At the moment it does feel like the Group of Adventurers type in my opinion. The characters are equally important.
I wouldn't mind being a bit more special with my custom made character, especially since the backstories of the companions are very overwhelming compared to our poor custom made characters.
It would be nice to choose from a variety of backstories or just select none, If someone wants to have a really blank state.
I agree, that currently it feels, like the CC is unfinished and Tav too simple. I like more varieties for my character and not just in looks.
And yes, If we have to get origin characters, it would be good to be able to test them in EA.
Short offtopic: Harry Potter isn't about a single main character, the whole story is a group effort. Harry is chosen, like Frodo in LotR, but without his friends he wouldn't have come far. So while the book ist mostly written from Harrys PoV, I feel like they are about an adventuring group. (Just my 2 cents as a Potterhead).
