The old style auto added points based on what attributes you used. So if you leveled destruction a lot during level 5 you could get a boosted willpower or Intelligence stat when you leveled up. It was a little chaotic. Now you have 12 stat points(virtues) you can add to whatever 3 attributes you want maxed at 5 points per attribute.

Feels on brand for Bethesda to secret release this just before skyblivion mod finally gets near their release date. Kind of feels like a slap in the face to the community. I guess we will get a who did it better comparison.
