I'm firmly in the point buy camp myself.
I love me some random results....but I like randomness that has a single, one time aspect.
I still remember the time my character used all of these special magical ingredients to hurl a 12d6 fireball....in which I rolled 15 damage....half because he saved....-5 for fire resistance....yep I did 2 damage on a fireball! That was hilarious, we still talk about it to this day.
But having a few rolls affect every other roll that character makes for the rest of the game...its too much imo.
