ForceUser said:The design team's theory on that is that you get to attack more often with dual wield. You have more attacks, so I guess in 3.0 that meant Power Attack worked out mathematically better for dual-wielders than greatsword wielding barbarians. I'm sure you can agree that just ain't right. Hence the change.
If that was the case, then either raising the bonus to +2 per point of PA for two-handed weapons, or eliminating PA for light weapons would have fixed that problem. It wasn't necessary to do both.
