Rolling has never made things 'unbalanced'. That's a myth. Rolling adds to the fun, challenge, randomness, coolness, sexyness, brilliance, awesomeness, freeing, imaginative, intellectual, and fantasticness of dnd. It's that great!!!

In comparision: point buy is boring, bland, unimaginative, stagnant, unbalanced, garbage, awful, lazy, easy, unintellectual, ugly, unsexy, not cool, limiting, and majes gane worse than they should be.
