I think the entire point is to grow into your character, rather than start with it fixed in stone. Personally I would rather grow into a mage, warrior or thief, having farmer or useless third son of noble house as my past, than start as a fixed adventuring class, and continue in that vein.
Hopefully, with the perks and the open skill leveling, Character creation will be just as complex, but an on-going process, rather than being decided at the beginning.
I'm not trying to flame you, but I think you severely missed my point. I never said having a background and having character development were mutually exclusive. One OR the other
. No. You can still develop your character to kingdom come. I only thought it would be cool to have the chance to create your own badguy and your own reasons for disliking him, and making him a tad bit of a nuisance during the early part of your game between levels 6 and 12. No more, no less. You STILL define yourself and your character by how you choose to play. The backstory element has nothing to do with character development. The fact is that this is just a person from your past and they are showing up like any quest ... except that it is stretched out for a longer period of time over 5-10 visitations spread between levels 6 through 12. You only see him 1-2 times per level. You battle, he taunts you, you hate him a bit more, and then he gets away again.
And as I said before, if you didn't want him in there, you needn't check "enable backstory" in the startup window. No muss no fuss.
