Which is fine but it just amounts to: "I don't care"
I am not forcing you to care. "I" care.
The reason why, is simply because you can still access their content with your companions. So pick the 4 guys you like the most you will still see their content.
The fact it might 3rd person view for your companion isn't a loss of content.
If you feel like playing again, choose one custom and the one you didn't pick the first time.
I prefer custom character because I don't feel like having to roleplay a predetermined character and I feel like having more freedom with the character's development.
I actually like that it since gives me more content to see on subsequent playthrough. That is why I don't really get the seemingly angry rant.
