Well it's an RPG, you'll have party members, so the Origin characters will not go away.
But I don't see why I souldn't be allowed to alter their stats, it's not what makes them "them". You get to make every other leveling choice for them. The first level ability distiribution is a massive part of a character design, poor choices here will hamper a character for the whole campaign.
You get 4-6 more ability points after this, that's not a whole lot, especially if you have to spend 2 of them to fix the bad character designs.
