Regarding torc's point, I strongly disagree that most characters have 'unplayable stats' - It might be far more challenging to start with low stats but the vast majority of characters are very playable regardless (though you might have to choose an easier start instead of the SMC/UD run for example). While many people may reroll (a lot?) and it is practically necessary for some challenges, it should not be considered standard to do so. That being said, torc brings up a great point in that the massive randomness is a major barrier to newer players (especially since it is not clear to them how good/bad a character is). In this respect, I think point-buy generating mostly average characters is quite good as an easier fast option for newer players (than pure random).
