In D&D, the stats contribute to the roll modifier, which I honestly never liked. If my character has a 13 in some stat, and someone has a 12, my character should be just a little bit better in that stat, instead of exactly the same. I suppose the actual difference might be negligible, but it's still a bit annoying.

But the whole point of that is to avoid super high modifiers. By grouping them you need to get much higher stats before you get a roll modifier increase. Otherwise levels would only matter early on.
