The stats don't matter with regard to play balance. They matter for preference in that they better model a realistic character. Arrays/point buy tend to make the vast majority of fighters stupid and/or uncharismatic. That's absurd, but it's what the array/point buy environment creates.
No, that's what people assigning points as they see fit does. The only absurdity here is that you insist on claiming that your one-true-wayism is some kind of mystical truth.
We all have preferences. I don't care if you roll for stats, but it's annoying that you feel compelled to slam people for generating stats differently.
